Cryptocurrency economics

James Chanos , known as the "dean of the short sellers", believes that bitcoin and other cryptocurrencies are a mania and useful only for tax avoidance or otherwise hiding income from the government. Bitcoin "is simply a security speculation game masquerading as a technological breakthrough in monetary policy".

Two lead software developers of bitcoin, Gavin Andresen [87] and Mike Hearn, [88] have warned that bubbles may occur. On 13 September , Jamie Dimon referred to bitcoin to as a "fraud", [89] comparing it to pyramid schemes , and stated that JPMorgan Chase would fire employees trading while the company released a report critical of the cryptocurrency. Some journalists, [94] economists, [95] [96] and the central bank of Estonia [97] have voiced concerns that bitcoin is a Ponzi scheme.

In , Eric Posner , a law professor at the University of Chicago, stated that "a real Ponzi scheme takes fraud; bitcoin, by contrast, seems more like a collective delusion. In billionaire Howard Marks investor referred to bitcoin as a pyramid scheme. Zero Hedge claimed that the same day Dimon made his statement, JP Morgan also purchased a large amount of bitcoins for its clients.

Financial journalists and analysts, economists, and investors have attempted to predict the possible future value of bitcoin. In April , economist John Quiggin stated, "bitcoins will attain their true value of zero sooner or later, but it is impossible to say when".

In December , finance professor Mark T. The "death" of bitcoin has been proclaimed numerous times. Forbes magazine declared bitcoin "dead" in June , [] followed by Gizmodo Australia in August Peter Greenhill, Director of E-Business Development for the Isle of Man, commenting on the obituaries paraphrased Mark Twain saying "reports of bitcoin's death have been greatly exaggerated".

Some economists have responded positively to bitcoin while others have expressed skepticism. Velde, Senior Economist at the Chicago Fed , described it as "an elegant solution to the problem of creating a digital currency". Louis , stated that bitcoin is a threat to the establishment, which he argues is a good thing for the Federal Reserve System and other central banks , because it prompts these institutions to operate sound policies.

Free software movement activist Richard Stallman has criticized the lack of anonymity and called for reformed development. Marcus calls bitcoin a "great place to put assets" but claims it will not be a currency until price volatility is reduced. In November , three US government officials testified at senate hearings that "Bitcoin has legitimate uses".

According to the Washington Post , "Most of the other witnesses echoed those sentiments. Most bitcoin transactions take place on a cryptocurrency exchange , rather than being used in transactions with merchants. Prices are not usually quoted in units of bitcoin and many trades involve one, or sometimes two, conversions into conventional currencies.

In and bitcoin's acceptance among major online retailers included only three of the top U. Bitcoin is "not actually usable" for retail transactions because of high costs and the inability to process chargebacks , according to Nicholas Weaver, a researcher quoted by Bloomberg.

High price volatility and transaction fees make paying for small retail purchases with bitcoin impractical, according to economist Kim Grauer. Bitcoin started to be accepted also for real estate payments in late The first recorded sale of a house in exchange for bitcoin happened in September , when Texas based Kuper Sotheby's International Realty brokered the deal using bitpay. Two months later, a first recorded sale of apartment in the world and first real estate property in Europe was sold for bitcoin in November in the Czech republic.

The Czech real estate agency HOME Hunters brokered a deal of a 3-room apartment for a Russian buyer without using a payment service providers at all. Some U. Merchants accepting bitcoin, such as Dish Network, use the services of bitcoin payment service providers such as BitPay or Coinbase. When a customer pays in bitcoin, the payment service provider accepts the bitcoin on behalf of the merchant, directly converts it, and sends the obtained amount to merchant's bank account, charging a fee of less than 1 percent for the service.

Due to the design of bitcoin, all retail figures are only estimates. Bitcoin companies have had difficulty opening traditional bank accounts because lenders have been leery of bitcoin's links to illicit activity. The request was motivated by oil company's goal to pay its suppliers.

Some Argentinians have bought bitcoins to protect their savings against high inflation or the possibility that governments could confiscate savings accounts. Other methods of investment are bitcoin funds. The first regulated bitcoin fund was established in Jersey in July and approved by the Jersey Financial Services Commission. Forbes named bitcoin the best investment of To improve access to price information and increase transparency, on 30 April Bloomberg LP announced plans to list prices from bitcoin companies Kraken and Coinbase on its , subscription financial data terminals.

The number of bitcoin millionaires is uncertain as people can have more than one wallet. Bitcoin is useful for crowdfunding. He was shown by local TV company with a broadsheet "Hi mom, send bitcoins". The decentralization of money offered by virtual currencies like bitcoin has its theoretical roots in the Austrian school of economics , [] especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined , in which he advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.

Bitcoin appeals to tech-savvy libertarians , because it so far exists outside the institutional banking system and the control of governments. Bitcoin's appeal reaches from left wing critics, "who perceive the state and banking sector as representing the same elite interests, [ From Wikipedia, the free encyclopedia.

The community looks to the Bitcoin core group for leadership concerning the direction of the community. An alternative approach would be for the community to agree about the specification for the community, and then let independent teams write clients that implement the specification.

The simple fact that Bitcoin has such a dominant benchmark client means that evolution can occur more quickly, even though it might also have hidden prices. As an instance, the community has to put a lot of trust in the Bitcoin core developers to not create bad adjustments to the network. A less concentrated approach to cryptocurrency growth would slow down growth, which would prevent any adjustments to the community without full deliberation of the community.

Miners also play an significant role in governance. Because miners cryptographically guard against double spending, their consensus on what counts as a legitimate transaction is essential for a cryptocurrency to function. The majority of miners must embrace any change into Bitcoin, and so the miners have the ability to impose a check on programmers. Miners also exert influence through mining pools. Miners combine pools in order to make a more consistent payout.

Just one miner working alone might go for some time without finding a block. However, if miners pool their job and divide their rewards, they could make monthly premiums. Mining pools increase complications. For example, the biggest Bitcoin mining pool often includes a third or more of the computing power of the Bitcoin network. Double spending would destroy confidence in the Bitcoin network and could probably make the price of bitcoins to plummet.

Thus, we observe a few self-regulation by the pools, which are heavily invested in the achievement. Whenever the top pool begins to approach 40 percent or so of computing power of this network, some participants depart the pool and join a different one. So far this standard has escalated, but many in the area are worried about mining pool attention.

Lately, the ghash. There is no evidence that the pool used its place to double invest, but many observers were alerted that it had been able to occur. Concentrated mining pools have advantages in addition to dangers. Within minutes of this realisation that there was a fork, the center programmers gathered in a chat room and determined that the system must revert to the 0.

Over the next few hours, they could confer with the significant mining pool operators and persuade them to switch back into 0. The fact that mining pools are relatively concentrated meant that it had been relatively easy to organize in the crisis. In about seven hours, the 0. Although it remains unclear if mt.

Customers give banks their money for, among other reasons, secure safekeeping and the ability to send payment to a payee located somewhere else originally using paper checks or bills of exchange. Historically and today, maintaining accurate ledgers of accounts is a vital tool for providing these services. It allows people to hold money as numerical data stored in a ledger instead of as a physical thing that can be lost or stolen.

In the simplest form, a payment system works by a bank recording how much money an individual has access to and, upon instruction, making appropriate additions and reductions to that amount. The mechanics of the modern payment system, in which instructions are sent and records are stored electronically, are covered in more detail in the following section, " The Electronic Exchange of Money. Otherwise, an individual's money could be lost or stolen if a bank records the payer's account as having an inaccurately low amount or transfers value without permission.

A number of mechanisms can create trust in banks. For example, a bank has a market incentive to be accurate, because a bank that does not have a good reputation for protecting customers' money and processing transactions accurately will lose customers. In addition, governments typically subject banks to laws and regulations designed in part to ensure that banks are run well and that people's money is safe in them.

Today, money is widely exchanged electronically, but electronic payments systems can be subject to certain difficulties related to lack of scarcity a digital file can be copied many times over, retaining the exact information as its predecessor and lack of trust between parties.

Electronic transfers of money are subject to what observers refer to as the double spending problem. In an electronic transfer of money, a payer may wish to send a digital file directly to a payee in the hopes that the file will act as a transfer of value. However, if the payee cannot confirm that the payer has not sent the same file to multiple other payees, the transfer is problematic.

Because money in such a system could be double or any number of times spent, the money would not retain its value. As described in the preceding section, this problem traditionally has been resolved by involving at least one centralized, trusted intermediary—such as a private bank, government central bank, or other financial institution—in electronic transfers of money. The trusted intermediaries maintain private ledgers of accounts recording how much money each participant holds.

To make a payment, an electronic message or messages is sent to an intermediary or to and between various intermediaries, instructing each to make the necessary changes to its ledgers. The intermediary or intermediaries validate the transaction, ensure the payer has sufficient funds for the payment, deduct the appropriate amount from the payer's account, and add that amount to the payee's account. Those banks then make the appropriate changes to their account ledgers possibly using the Federal Reserve's payment system reflecting that value has been transferred from the purchaser's account to the seller's account.

Significant costs and physical infrastructure underlie systems for electronic money transfers to ensure the systems' integrity, performance, and availability. For example, payment system providers operate and maintain vast electronic networks to connect retail locations with banks, and the Federal Reserve operates and maintains networks to connect banks to itself and each other.

In general, these intermediaries are highly regulated to ensure safety, profitability, consumer protection, and financial stability. Intermediaries recoup the costs associated with these systems and earn profits by charging fees directly when the system is used such as the fees a merchant pays to have a card reading machine and on each transaction or by charging fees for related services such as checking account fees.

In addition, intermediaries generally are required to provide certain protections to consumers involved in electronic transactions. Notably, certain individuals may lack access to electronic payment systems. To use an electronic payment system, a consumer or merchant generally must have access to a bank account or some retail payment service, which some may find cost prohibitive or geographically inconvenient, resulting in underbanked or unbanked populations i.

The use of electronic payment services generates a huge amount of data about an individual's financial transactions. This information could be accessed by the bank, law enforcement provided proper procedures are followed , 32 or nefarious actors provided they are capable of circumventing the intermediaries' security measures. Cryptocurrencies—such as Bitcoin, Ether, and Litecoin—provide an alternative to this traditional electronic payment system.

As noted above, cryptocurrency acts as money in an electronic payment system in which a network of computers, rather than a single third-party intermediary, validates transactions. In general, these electronic payment systems use public ledgers that allow individuals to establish an account with a pseudonymous name known to the entire network—or an address corresponding to a public key—and a passcode or private key that is paired to the public key and known only to the account holder.

The buying party will unlock the cryptocurrency they will use as payment with their private key, allowing the selling party to lock it with their private key. In addition, certain companies offer applications or interfaces that users can download onto a device to make transacting in cryptocurrencies more user-friendly. Cryptocurrency platforms often use blockchain technology to validate changes to the ledgers.

Specifically, before any transaction is entered into the ledger and the ledger is irreversibly changed, some member of the network must validate the transaction. In certain cryptocurrency platforms, validation requires the member to solve an extremely difficult computational decryption. Once the transaction is validated, it is entered into the ledger. These protocols secure each transaction by using digital signatures to validate the identity of the two parties involved and to validate that the entire ledger is secure so that any changes in the ledger are visible to all parties.

In this system, parties that otherwise do not know each other can exchange something of value i. Cryptocurrency platforms often incentivize users to perform the functions necessary for validation by awarding them newly created units of the currency for successful computations often the first person to solve the problem is given the new units , although in some cases the payer or payee also is charged a fee that goes to the validating member.

In general, the rate at which new units are created—and therefore the total amount of currency in the system—is limited by the platform protocols designed by the creators of the cryptocurrency. Because users of the cryptocurrency platform must perform work to extract the scarce unit of value from the platform, much as people do with precious metals, it is said that these users mine the cryptocurrencies.

Alternatively, people can acquire cryptocurrency on certain exchanges that allow individuals to purchase cryptocurrency using official government-backed currencies or other cryptocurrencies. Cryptographers and computer scientists generally agree that cryptocurrency ledgers that use blockchain technology are mathematically secure and that it would be exceedingly difficult—approaching impossible—to manipulate them.

However, hackers have exploited vulnerabilities in certain exchanges and individuals' devices to steal cryptocurrency from the exchange or individual. Analyzing data about certain characteristics and the use of cryptocurrency would be helpful in measuring how well cryptocurrency functions as an alternative source of payment and thus its future prospects for functioning as money.

However, conducting such an analysis currently presents challenges. The decentralized nature of cryptocurrencies makes identifying authoritative sources of industry data difficult. In addition, the recent proliferation of cryptocurrency adds additional challenges to performing industry-wide analysis. Because of these challenges, an exhaustive quantitative analysis of the entire cryptocurrency industry is beyond the scope of this report. Instead, the report uses Bitcoin—the first and most well-known cryptocurrency, the total value of which accounts for almost two-thirds of the industry as a whole 42 —as an illustrative example.

Examining recent trends in Bitcoin prices, value in circulation, and number of transactions may shed some light on how well cryptocurrencies in general have been performing as an alternative payment system. The rapid appreciation in cryptocurrencies' value in likely contributed to the recent increase in public interest in these currencies.

Since that time, the price of a Bitcoin remained volatile. Other major cryptocurrencies, such as Ether and Litecoin, have had similar price movements. Figure 1. Cryptocurrency Values. Although these statistics drive interest in and are central to the analysis of cryptocurrencies as investments , they reveal little about the prevalence of cryptocurrencies' use as money. Recent volatility in the price of cryptocurrencies suggests they function poorly as a unit of account and a store of value two of the three functions of money discussed in " The Functions of Money ," above , an issue covered in the " Potential Challenges to Widespread Adoption " section of this report.

Nevertheless, the price or the exchange rate of a currency in dollars at any point in time rather than over time does not have a substantive influence on how well the currency serves the functions of money.

The number of Bitcoin transactions, by contrast, can serve as an indicator—though a flawed one 46 —of the prevalence of the use of Bitcoin as money. This number indicates how many times a day Bitcoins are transferred between accounts.

One industry data source indicates that the number of Bitcoin transactions averaged about , per day globally in For example, the Automated Clearing House—an electronic payments network operated by the Federal Reserve Bank and the private company Electronic Payments Network—processed more than 69 million transactions per day on average in the fourth quarter of The previous section illustrates that the use of cryptocurrencies as money in a payment system is still quite limited compared with traditional systems.

However, the invention and growth in awareness of cryptocurrencies occurred only recently. Some observers assert that cryptocurrencies' potential benefits will be realized in the coming years or decades, which will lead to their widespread adoption. Later sections—" Potential Challenges to Widespread Adoption " and " Potential Risks Posed by Cryptocurrencies "—discuss certain potential challenges to widespread adoption of cryptocurrencies and some potential risks cryptocurrencies pose.

As discussed in the " The Electronic Exchange of Money " section, traditional monetary and electronic payment systems involve a number of intermediaries, such as government central banks and private financial institutions. To carry out transactions, these institutions operate and maintain extensive electronic networks and other infrastructure, employ workers, and require time to finalize transactions.

To meet costs and earn profits, these institutions charge various fees to users of their systems. Advocates of cryptocurrencies hope that a decentralized payment system operated through the internet will be less costly than the tradition al payment systems and existing infrastructures.

Cryptocurrency proponents assert that cryptocurrency may provide an especially pronounced cost advantage over traditional payment systems for international money transfers and payments. Sending money internationally generally involves further intermediation than domestic transfers, typically requiring transfers between banks and other money transmitters in different countries and possibly exchanges of one national currency for another.

Proponents assert that cryptocurrencies could avoid these particular costs because cryptocurrency transactions take place over the internet—which is already global—and are not backed by government-fiat currencies. Nevertheless, it is difficult to quantify how much traditional payment systems cost and what portion of those costs is passed on to consumers. Performing such a quantitative analysis is beyond the scope of this report. As discussed in the " Traditional Money " section, traditional payment systems require that government and financial institutions be credible and have people's trust.

Even if general trust in those institutions is sufficient to make them credible in a society, certain individuals may nevertheless mistrust them. For people who do not find various institutions sufficiently trustworthy, cryptocurrencies could provide a desirable alternative. In countries with advanced economies, such as the United States, mistrust may not be as prevalent although not wholly absent as in other countries.

Typically, developed economies are relatively stable and have relatively low inflation; often, they also have carefully regulated financial institutions and strong government institutions. Not all economies share these features. Thus, cryptocurrencies may experience more widespread adoption in countries with a higher degree of mistrust of existing systems than in countries where there is generally a high degree of trust in existing systems.

A person may mistrust traditional private financial institutions for a number of reasons. An individual may be concerned that an institution will go bankrupt or otherwise lose his or her money without adequately apprising him or her of such a risk or while actively misleading him or her about it.

Financial institutions store this information and information about the transactions linked to this identity. Under certain circumstances, they may analyze or share this information, such as with a credit-reporting agency. In some instances hackers have stolen personal information from financial institutions, causing concerns over how well these institutions can protect sensitive data.

Certain individuals also may mistrust a government's willingness or ability to maintain a stable value of a fiat currency. Because fiat currency does not have intrinsic value and, historically, incidents of hyperinflation in certain countries have seen government-backed currencies lose most or nearly all of their value, some individuals may judge the probability of their fiat money losing a significant portion of its value to be undesirably high in some circumstances.

These individuals may place greater trust in a decentralized network using cryptographic protocols that limit the creation of new money than in government institutions. The appropriate policy approach to cryptocurrencies likely depends, in part, on how prevalent these currencies become. For cryptocurrencies to deliver the potential benefits mentioned above, people must use them as money to some substantive degree. After all, as money, cryptocurrencies would do little good if few people and businesses accept them as payment.

For this reason, currencies are subject to network effects , wherein their value and usefulness depends in part on how many people are willing to use them. Recall that how well cryptocurrency serves as money depends on how well it serves as 1 a medium of exchange, 2 a unit of account, and 3 a store of value.

Several characteristics of cryptocurrency undermine its ability to serve these three interrelated functions in the United States and elsewhere. Currently, a relatively small number of businesses or individuals use or accept cryptocurrency for payment. As discussed in the " The Price and Usage of Cryptocurrency " section, there were , transactions involving Bitcoin per day globally out of the billions of financial transactions that take place in , and a portion of those transactions involved people buying Bitcoins for the purposes of holding them as an investment rather than as payment for goods and services.

Unlike the dollar and most other government-backed currencies, cryptocurrencies are not legal tender, meaning creditors are not legally required to accept them to settle debts. As previously mentioned, the recent high volatility in the price of many cryptocurrencies undermines their ability to serve as a unit of account and a store of value. Cryptocurrencies can have significant value fluctuations within short periods of time; as a result, pricing goods and services in units of cryptocurrency would require frequent repricing and likely would cause confusion among buyers and sellers.

In comparison, the annualized inflation of prices in the U. Whether cryptocurrency systems are scalable —meaning their capacity can be increased in a cost-effective way without loss of functionality—is uncertain. As discussed in the " The Price and Usage of Cryptocurrency " section, the platform of the largest by a wide margin cryptocurrency, Bitcoin, processes a small fraction of the overall financial transactions parties engage in per day.

The overwhelming majority of such transactions are processed through established payment systems. As well, Bitcoin's processing speed is still comparatively slow relative to the nearly instant transaction speed many electronic payment methods, such as credit and debit cards, achieve. For example, blocks of transactions are published to the Bitcoin ledger every 10 minutes, but because a limited number of transactions can be added in a block, it may take over an hour before an individual transaction is posted.

Part of the reason for the relatively slow processing speed of certain cryptocurrency transactions is the large computational resources involved with mining—or validating—transactions. When prices for cryptocurrencies were increasing rapidly, many miners were incentivized to participate in validating transactions, seeking to win the rights to publish the next block and collect any reward or fees attached to that block.

This incentive led to an increasing number of miners and to additional investment in faster computers by new and existing miners. The combination of more miners and more energy required to power their computers led to ballooning electricity requirements. However, as the prices of cryptocurrencies have deflated, validating cryptocurrency transactions has become a less rewarding investment for miners; consequently, fewer individuals participate in mining operations.

The energy consumption required to run and cool the computers involved in cryptocurrency mining is substantial. Some estimates indicate the daily energy needs of the Bitcoin network are comparable to the needs of a small country, such as Ireland. In general, when a buyer of a good or a service provided remotely sends a cryptocurrency to another account, that transaction is irreversible and made to a pseudonymous identity. Although a cryptocurrency platform validates that the currency has been transferred, the platform generally does not validate that a good or service has been delivered.

Unless a transfer is done face-to-face, it will involve some degree of trust between one party and the other or a trusted intermediary. If the buyer transfers the Bitcoin before she has received the item, she takes on the risk that the seller will never ship the item to her; if that happened, the buyer would have little, if any, recourse. Conversely, if the seller ships the item before the buyer has transferred the Bitcoin, he assumes the risk that the buyer never will transfer the Bitcoin.

These risks could act as a disincentive to parties considering using cryptocurrencies in certain transactions and thus could hinder cryptocurrencies' ability to act as a medium of exchange. As mentioned in the " Banks: Transferring Value Through Intermediaries " section, sending cash to someone in another location presents a similar problem, which historically has been solved by using a trusted intermediary. In response to this problem, several companies offer cryptocurrency escrow services.

Typically, the escrow company holds the buyer's cryptocurrency until delivery is confirmed. Only then will the escrow company pass the cryptocurrency onto the seller. Although an escrow service may enable parties who otherwise do not trust each other to exchange cryptocurrency for goods and services, the use of such services reintroduces the need for a trusted third-party intermediary in cryptocurrency transactions.

As with the use of intermediaries in traditional electronic transactions discussed above, both a buyer and a seller in a cryptocurrency transaction would have to trust that the escrow company will not abscond with their cryptocurrency and is adequately protected against hacking.

For cryptocurrencies to gain widespread acceptance as payment systems and displace existing traditional intermediaries, new procedures and intermediaries such as those described in this section may first need to achieve a sufficient level of trustworthiness and efficiency among the public. If cryptocurrencies ultimately require their own system of intermediaries to function as money, questions may arise about whether this requirement defeats their original purpose.

Policymakers developed most financial laws and regulations before the invention and subsequent growth of cryptocurrencies, which raises questions about whether existing laws and regulations appropriately and efficiently address the risks posed by cryptocurrency. Some of the more commonly cited risks include the potential that cryptocurrencies will be used to facilitate criminal activity and the lack of consumer protections applicable to parties buying or using cryptocurrency.

Each of these risks is discussed below. Criminals and terrorists are more likely to conduct business in cash and to hold cash as an asset than to use financial intermediaries such as banks, in part because cash is anonymous and allows them to avoid establishing relationships with and records at financial institutions that may be subject to anti-money laundering reporting and compliance requirements.

This marketplace and Bitcoin escrow service facilitated more than , illegal drug sales from approximately January to October , at which time the government shut down the website and arrested the individuals running the site. Criminal use of cryptocurrency does not necessarily mean the technology is a net negative for society, because the benefits it provides could exceed the societal costs of the additional crime facilitated by cryptocurrency.

In addition, law enforcement has existing authorities and abilities to mitigate the use of cryptocurrencies for the purposes of evading law enforcement. Recall that cryptocurrency platforms generally function as an immutable, public ledger of accounts and transactions. Thus, every transaction ever made by a member of the network is relatively easy to observe, and this characteristic can be helpful to law enforcement in tracking criminal finances.

Although the accounts may be identified with a pseudonym on the cryptocurrency platform, law enforcement can exercise methods involving analysis of transaction patterns to link those pseudonyms to real-life identities. For example, it may be possible to link a cryptocurrency public key with a cryptocurrency exchange customer.

In addition to law enforcement's abilities to investigate crime, the government has authorities to subject cryptocurrency exchanges to regulation related to reporting suspicious activity. The Department of the Treasury's Financial Crimes Enforcement Network FinCEN has issued guidance explaining how its regulations apply to the use of virtual currencies —a term that refers to a broader class of electronic money that includes cryptocurrencies.

FinCEN has indicated that an exchanger "a person engaged as a business in the exchange of virtual currency for real currency, funds, or other virtual currency" and an administrator "a person engaged as a business in issuing [putting into circulation] a virtual currency, and who has the authority to redeem [to withdraw from circulation] such virtual currency" generally qualify as money services businesses MSBs subject to federal regulation.

The specific requirements generally vary across different states; 80 a state-by-state analysis is beyond the scope of this report. A number of bills related to the criminal use of cryptocurrencies and ways of improving the ability of government agencies to address this problem have seen action in the th Congress:. As with money laundering, individuals could potentially use a pseudonymous, decentralized platform and thus avoid generating records at traditional financial institutions as a mechanism for hiding income from tax authorities.

The IRS has issued guidance stating that virtual currencies are treated as property as opposed to currency for tax purposes, meaning users owe taxes on any realized gains whenever they dispose of virtual currency, including when they use it to purchase goods and services. By November , the IRS had come to believe that cryptocurrency gains were being underreported, finding that between and only to tax returns declared such gains.

In July , the IRS sent letters to 10, taxpayers with cryptocurrency transactions alerting them that they potentially had not met their reporting requirements although the IRS did not explicitly link the letters to the Coinbase case. The prevalence of using cryptocurrency to avoid taxes is uncertain at this time. The language in certain variations of the letters the IRS sent indicates the IRS did not think these recipients' failure to pay was intentional.

Rather, investors may have been seeking to profit from cryptocurrency, and then not paying taxes on the gains after the fact, rather than primarily seeking to hide assets from tax authorities. Indeed, cryptocurrencies' poor performance as a store of value may make them a poor instrument for this purpose at this time. In addition, prominent U. Nevertheless, the difficulty the IRS experienced with the largest and most well-known cryptocurrency exchange may suggest that individuals who seek to evade taxes might look to cryptocurrency as a possible avenue.

Although it is outside the scope of this report, another potential reason a person or entity may want to move money or assets while avoiding engagement with traditional financial institutions could be to evade financial sanctions. For example, the Venezuelan government has launched a digital currency with the stated intention of using it to evade U. Nelson and Liana W. Although there is no overarching regulation or regulatory framework specifically aimed at providing consumer protections in cryptocurrencies markets, numerous consumer protection laws and regulatory authorities at both the federal and state levels are applicable to cryptocurrencies.

Whether these regulations adequately protect consumers and whether existing regulation is unnecessarily burdensome are topics subject to debate. This section will examine some of these consumer protections and present arguments related to these debated issues. A related concern has to do with whether investors in certain cryptocurrency instruments such as initial coin offerings —wherein companies developing an application or platform issue cryptocurrencies or other digital or virtual currency that are or will be used on the application or platform—or cryptocurrency derivatives contracts are adequately informed of risk and protected from scams.

However, this secondary use of cryptocurrency as investment vehicles is different from the use of cryptocurrencies as money, and it is beyond the scope of this report. No federal consumer protection law specifically targets cryptocurrencies. However, the way cryptocurrencies are sold, exchanged, or marketed can subject cryptocurrency exchanges or other cryptocurrency-related businesses to generally applicable consumer protection laws.

In recent years, the FTC has brought a number of enforcement actions against cryptocurrency promoters and mining operations due to potential violations of Section 5 a. In addition, Title X of the Dodd-Frank Act grants the Consumer Financial Protection Bureau CFPB certain rulemaking, supervisory, and enforcement authorities to implement and enforce certain federal consumer financial laws that protect consumers from "unfair, deceptive, or abusive acts and practices.

Although the CFPB has not actively exercised regulatory authorities in regard to the cryptocurrency industry to date, the agency is accepting cryptocurrency-related complaints and previously has indicated it would enforce consumer financial laws in appropriate cases. Both the FTC and the CFPB have made available informational material, such as consumer advisories, to educate consumers about potential risks associated with transacting in cryptocurrencies.

In addition, all states have laws against deceptive acts and practices, and state regulators have enforcement authorities that could be exercised against cryptocurrency-related businesses. For example, money transmitters generally must maintain some amount of low-risk investments and surety bonds—which are akin to an insurance policy that pays customers who do not receive their money—as safeguards for customers in the event they do not receive money that was to be sent to them.

Certain observers assert that consumers may be especially susceptible to being deceived or misinformed when dealing in cryptocurrencies. Although certain federal laws and regulations intended to protect consumers such as those described in " Applicable Regulation ," above do apply to certain cryptocurrency transactions, others may not. Some of those laws and regulations that do not currently apply are specifically designed to protect consumers engaged in the electronic transfer of money, require certain disclosures about the terms of financial transactions, and require transfers to be reversed under certain circumstances.

The application of state laws and consumer protections to cryptocurrency transactions is not uniform, and the stringency of regulation can vary across states. If Congress decides current consumer protections are inadequate, policy options could include extending the application of certain electronic fund transfer protections to consumers using cryptocurrency exchanges and service providers and granting federal agencies additional authorities to regulate those businesses.

Proponents of cryptocurrencies have asserted that the application of a state-by-state consumer protection regulatory regime to cryptocurrency exchanges is unnecessarily onerous. They note that certain state regulations applicable to these exchanges are designed to address risks presented by traditional money transmission transactions i.

For example, the previously mentioned requirements to maintain low-risk investments and surety bonds are intended to ensure customers will receive transmitted money. Supporters of cryptocurrencies further argue that if the United States does not reduce the regulatory burdens involved in cryptocurrency exchanges, the country will be at a disadvantage relative to others in regard to the development of cryptocurrency systems and platforms.

If Congress decides the current regulatory framework is unnecessarily burdensome, some argue that one policy option would be to enact federal law applicable to cryptocurrency exchanges or virtual currency exchanges more broadly that preempts state-level requirements. As discussed in the " Government Authority: Fiat Money " section, in the United States, the Federal Reserve has the authority to conduct monetary policy with the goals of achieving price stability and low unemployment.

The central banks of other countries generally have similar authorities and goals. Some central bankers and other experts and observers have speculated that the widespread adoption of cryptocurrencies could affect the ability of the Federal Reserve and other central banks to implement and transmit monetary policy, and some have suggested that these institutions should issue their own digital, fiat currencies.

The mechanisms through which central banks implement monetary policy can be technical, but at the most fundamental level these banks conduct monetary policy by regulating how much money is in circulation in an economy. Currently, the vast majority of money circulating in most economies is government-issued fiat money, and so governments particularly credible governments in countries with relatively strong, stable economies have effective control over how much is in circulation.

However, if one or more additional currencies that the government did not control such as cryptocurrencies were also prevalent and viable payment options, their prevalence could have a number of implications. The widespread adoption of such payment options would limit central banks' ability to control inflation, as they do now, because actors in the economy would be buying, selling, lending, and settling in cryptocurrency.

Central banks would have to make larger adjustments to the fiat currency to have the same effect as previous adjustments, or they would have to start buying and selling the cryptocurrencies themselves in an effort to affect the availability of these currencies in the economy.

Because cryptocurrency circulates on a global network, the actions of one country that buys and sells cryptocurrency to control its availability could have a destabilizing effect on other economies that also widely use that cryptocurrency; in this way, one country's approach to cryptocurrency could undermine price stability or exacerbate recessions or overheating in another country.

For example, as economic conditions in one country changed, that country would respond by attempting to alter its monetary conditions, including the amount of cryptocurrency in circulation. However, the prescribed change for that economy would not necessarily be appropriate in a country that was experiencing different economic conditions.

The supply of cryptocurrency in this second country nevertheless could be affected by the first country's actions. Another challenge in an economy with multiple currencies—as would be the case in an economy with a fiat currency and cryptocurrencies—is that the existence of multiple currencies adds difficulty to buyers and sellers making exchanges; all buyers and sellers must be aware of and continually monitor the value of different currencies relative to each other.

As an example, such a system existed in the United States for periods before the Civil War when banks issued their own private currencies. The inefficiency and costs of tracking the exchange rates and multiple prices in multiple currencies eventually led to calls for and the establishment of a uniform currency. On June 18, , Facebook announced that, with 28 other members, it had founded the Libra Association , which planned to launch a new cryptocurrency, called Libra.

President Trump and Treasury Secretary Mnuchin raised concerns about the Libra project, as did several Members of Congress during Senate Banking Committee and House Financial Services Committee hearings, although some Members were more welcoming of efforts to advance financial innovation.

As Congress considers its policy options regarding Libra, the proposal's future is uncertain. The Libra Association still has to develop the systems necessary to create, distribute, and allow payment in Libra. Furthermore, it has stated it will not make Libra available until regulators' concerns are addressed.

To date, governments Venezuela excepted generally have not been directly involved in the creation of cryptocurrencies; one of the central goals in developing the technology was to eliminate the need for government involvement in money creation and payment systems. However, cryptocurrency's decentralized nature is at the root of certain risks and challenges related to its lack of widespread adoption by the public and its use by criminals.

These risks and challenges have led some observers to suggest that perhaps central banks could use the technologies underlying cryptocurrencies to issue their own central bank digital currencies CBDCs to realize certain hoped-for efficiencies in the payment system in a way that would be "safe, robust, and convenient. Much of the discussion related to CBDCs is speculative at this point. The extent to which a central bank could or would want to create a blockchain-enabled payment system likely would be weighed against the consideration that these government institutions already have trusted digital payment systems in place.

Because of such considerations, the exact form that CBDCs would take is not clear; such currencies could vary across a number of features and characteristics. Nevertheless, some central banks are examining the idea of CBDCs and the possible benefits and issues they may present.

Numerous observers assert that CBDCs could provide certain benefits. For example, some proponents extend the arguments related to cryptocurrencies providing efficiency gains over traditional legacy systems to CBCDs; they contend that central banks could use the technologies underlying cryptocurrencies to deploy a faster, less costly government-supported payment system.

Observers have speculated that a CBDC could take the form of a central bank allowing individuals to hold accounts directly at the central bank. Advocates argue that a CBDC created in this way could increase systemic stability by imposing additional discipline on commercial banks. Because consumers would have the alternative of safe deposits made directly with the central bank, commercial banks would likely have to offer interest rates and security at a level necessary to attract deposits above any deposit insurance limit.

The increase of coins is limited by a pre-determined amount per cube. On Bitcoin, the pre-determined quantity is not scheduled to be constant over time, but rather is set to halve every , blocks, or about every four decades. You may not copy or distribute without permission. The dynamic between these players is as crucial to knowing Bitcoin as that of central banks, conventional monetary institutions and monetary politics is to comprehension fiat currency.

Bitcoin, like all other even moderately profitable users have a tendency to look with suspicion on cryptocurrency jobs that are closed source, that feature significant pre-mining to be able to benefit insiders, or that have other proprietary capabilities. Other expectations of the user community also inflict a check on developers. The community looks to the Bitcoin core group for leadership concerning the direction of the community. An alternative approach would be for the community to agree about the specification for the community, and then let independent teams write clients that implement the specification.

The simple fact that Bitcoin has such a dominant benchmark client means that evolution can occur more quickly, even though it might also have hidden prices. As an instance, the community has to put a lot of trust in the Bitcoin core developers to not create bad adjustments to the network.

A less concentrated approach to cryptocurrency growth would slow down growth, which would prevent any adjustments to the community without full deliberation of the community. Miners also play an significant role in governance. Because miners cryptographically guard against double spending, their consensus on what counts as a legitimate transaction is essential for a cryptocurrency to function.

The majority of miners must embrace any change into Bitcoin, and so the miners have the ability to impose a check on programmers. Miners also exert influence through mining pools. Miners combine pools in order to make a more consistent payout. Just one miner working alone might go for some time without finding a block.

However, if miners pool their job and divide their rewards, they could make monthly premiums. Mining pools increase complications. For example, the biggest Bitcoin mining pool often includes a third or more of the computing power of the Bitcoin network. Double spending would destroy confidence in the Bitcoin network and could probably make the price of bitcoins to plummet.

Thus, we observe a few self-regulation by the pools, which are heavily invested in the achievement. Whenever the top pool begins to approach 40 percent or so of computing power of this network, some participants depart the pool and join a different one. So far this standard has escalated, but many in the area are worried about mining pool attention. Lately, the ghash. There is no evidence that the pool used its place to double invest, but many observers were alerted that it had been able to occur.

Concentrated mining pools have advantages in addition to dangers. Within minutes of this realisation that there was a fork, the center programmers gathered in a chat room and determined that the system must revert to the 0. Over the next few hours, they could confer with the significant mining pool operators and persuade them to switch back into 0.

The fact that mining pools are relatively concentrated meant that it had been relatively easy to organize in the crisis.

F1 BETTING PREVIEW GOAL

It recommends using the term "crypto token. The People's Bank of China has stated that bitcoin "is fundamentally not a currency but an investment target". Journalists and academics also debate what to call bitcoin.

Some media outlets do make a distinction between "real" money and bitcoins, [22] while others call bitcoin real money. In addition to the above, bitcoin is also characterized as a payment system. According to research produced by Cambridge University in , there are between 2. The number of active users has grown significantly since there were 0. Bitcoins can be bought and sold both on- and offline. Participants in online exchanges offer bitcoin buy and sell bids. Bitcoin kiosks are machines connected to the Internet, allowing the insertion of cash in exchange for bitcoins.

According to Mark T. Attempting to explain the high volatility, a group of Japanese scholars stated that there is no stabilization mechanism. There are uses where volatility does not matter, such as online gambling, tipping, and international remittances. The price of bitcoins has gone through various cycles of appreciation and depreciation referred to by some as bubbles and busts. In particular, bitcoin mining companies, which are essential to the currency's underlying technology, are flashing warning signs.

Economic theory suggests that the volatility of the price of bitcoin will drop when business and consumer usage of bitcoin increases. This is a form of Metcalfe's law and suggests that the network was demonstrating network effects proportional to its level of user adoption. The investors Warren Buffett and George Soros have respectively characterized it as a "mirage" [60] and a "bubble"; [61] while the business executive Jack Ma has called it a "bubble".

In , Nobel laureate Robert J. Shiller stated that bitcoin "exhibited many of the characteristics of a speculative bubble"; [63] in , Shiller wrote that bitcoin was the best current example of a speculative bubble. Economist John Quiggin in said "bitcoins are the most demonstrably valueless financial asset ever created". Nobel laureate Paul Krugman wrote in that bitcoin is "a bubble wrapped in techno-mysticism inside a cocoon of libertarian ideology". He criticized it as a very slow and expensive means of payment, used mostly to buy blackmarket goods, without a "tether to reality".

Nobel laureate Richard Thaler emphasizes the irrationality in the bitcoin market that has led to the bubble, demonstrating the irrationality with the example of firms that have added the word blockchain to their names which have then had large increases in their stock price.

The extremely high volatility in bitcoin's price also is due to irrationality according to Thaler. Hart cited Christopher Sims 's work showing no intrinsic value to bitcoin. Heckman compared bitcoin to the tulip bubble. Deaton pointed to bitcoin's use by criminals.

Professor Nouriel Roubini of New York University has called bitcoin the "mother of all bubbles", [71] [72] writing that the underlying blockchain technology has "massive obstacles standing in its way", including a lack of "common and universal protocols" of the kind that enabled the early Internet. Early claims that bitcoin was a bubble focused on the lack of any intrinsic value of bitcoin. He stated "You really have to stretch your imagination to infer what the intrinsic value of Bitcoin is.

I haven't been able to do it. In Greenspan compared bitcoin to the Continental dollar , which ultimately collapsed. He said "Humans buy all sorts of things that aren't worth anything. People gamble in casinos when the odds are against them. It has never stopped anybody. Former Fed Chair Ben Bernanke in and outgoing Fed Chair Janet Yellen in have both expressed concerns about the stability of bitcoin's price and its lack of use as a medium of transactions.

Louis , stated, "Is bitcoin a bubble? Yes, if bubble is defined as a liquidity premium. American investor Warren Buffett warned investors about bitcoin in , "Stay away from it. It's a mirage, basically. He believes that bitcoin is a non-productive asset. Buffett's close associate Charlie Munger is even more direct in his disdain. Trading cryptocurrencies is "just dementia" according to Munger.

Bitcoin is "worthless" and a "turd". Did I make myself clear? There is nothing to support bitcoin except the hope that you will sell it to someone for more than you paid for it. George Soros , answering an audience question after a speech in Davos, Switzerland in , said that cryptocurrencies are not a store of value but are an economic bubble. Nevertheless, they may not crash due to the rising influence of dictators trying to "build a nest egg abroad".

James Chanos , known as the "dean of the short sellers", believes that bitcoin and other cryptocurrencies are a mania and useful only for tax avoidance or otherwise hiding income from the government. Bitcoin "is simply a security speculation game masquerading as a technological breakthrough in monetary policy".

Two lead software developers of bitcoin, Gavin Andresen [87] and Mike Hearn, [88] have warned that bubbles may occur. On 13 September , Jamie Dimon referred to bitcoin to as a "fraud", [89] comparing it to pyramid schemes , and stated that JPMorgan Chase would fire employees trading while the company released a report critical of the cryptocurrency. Some journalists, [94] economists, [95] [96] and the central bank of Estonia [97] have voiced concerns that bitcoin is a Ponzi scheme.

In , Eric Posner , a law professor at the University of Chicago, stated that "a real Ponzi scheme takes fraud; bitcoin, by contrast, seems more like a collective delusion. In billionaire Howard Marks investor referred to bitcoin as a pyramid scheme.

Zero Hedge claimed that the same day Dimon made his statement, JP Morgan also purchased a large amount of bitcoins for its clients. Financial journalists and analysts, economists, and investors have attempted to predict the possible future value of bitcoin. In April , economist John Quiggin stated, "bitcoins will attain their true value of zero sooner or later, but it is impossible to say when". In December , finance professor Mark T. The "death" of bitcoin has been proclaimed numerous times.

Forbes magazine declared bitcoin "dead" in June , [] followed by Gizmodo Australia in August Peter Greenhill, Director of E-Business Development for the Isle of Man, commenting on the obituaries paraphrased Mark Twain saying "reports of bitcoin's death have been greatly exaggerated".

Some economists have responded positively to bitcoin while others have expressed skepticism. Velde, Senior Economist at the Chicago Fed , described it as "an elegant solution to the problem of creating a digital currency". Louis , stated that bitcoin is a threat to the establishment, which he argues is a good thing for the Federal Reserve System and other central banks , because it prompts these institutions to operate sound policies.

Free software movement activist Richard Stallman has criticized the lack of anonymity and called for reformed development. Marcus calls bitcoin a "great place to put assets" but claims it will not be a currency until price volatility is reduced. In November , three US government officials testified at senate hearings that "Bitcoin has legitimate uses".

According to the Washington Post , "Most of the other witnesses echoed those sentiments. Most bitcoin transactions take place on a cryptocurrency exchange , rather than being used in transactions with merchants. Prices are not usually quoted in units of bitcoin and many trades involve one, or sometimes two, conversions into conventional currencies. In and bitcoin's acceptance among major online retailers included only three of the top U.

Bitcoin is "not actually usable" for retail transactions because of high costs and the inability to process chargebacks , according to Nicholas Weaver, a researcher quoted by Bloomberg. High price volatility and transaction fees make paying for small retail purchases with bitcoin impractical, according to economist Kim Grauer.

Bitcoin started to be accepted also for real estate payments in late The first recorded sale of a house in exchange for bitcoin happened in September , when Texas based Kuper Sotheby's International Realty brokered the deal using bitpay. Two months later, a first recorded sale of apartment in the world and first real estate property in Europe was sold for bitcoin in November in the Czech republic.

The Czech real estate agency HOME Hunters brokered a deal of a 3-room apartment for a Russian buyer without using a payment service providers at all. Some U. Merchants accepting bitcoin, such as Dish Network, use the services of bitcoin payment service providers such as BitPay or Coinbase. When a customer pays in bitcoin, the payment service provider accepts the bitcoin on behalf of the merchant, directly converts it, and sends the obtained amount to merchant's bank account, charging a fee of less than 1 percent for the service.

Due to the design of bitcoin, all retail figures are only estimates. Bitcoin companies have had difficulty opening traditional bank accounts because lenders have been leery of bitcoin's links to illicit activity. The request was motivated by oil company's goal to pay its suppliers.

Some Argentinians have bought bitcoins to protect their savings against high inflation or the possibility that governments could confiscate savings accounts. Other methods of investment are bitcoin funds. The first regulated bitcoin fund was established in Jersey in July and approved by the Jersey Financial Services Commission.

Forbes named bitcoin the best investment of To improve access to price information and increase transparency, on 30 April Bloomberg LP announced plans to list prices from bitcoin companies Kraken and Coinbase on its , subscription financial data terminals. The number of bitcoin millionaires is uncertain as people can have more than one wallet. Bitcoin is useful for crowdfunding. He was shown by local TV company with a broadsheet "Hi mom, send bitcoins".

The decentralization of money offered by virtual currencies like bitcoin has its theoretical roots in the Austrian school of economics , [] especially with Friedrich von Hayek in his book Denationalisation of Money: The Argument Refined , in which he advocates a complete free market in the production, distribution and management of money to end the monopoly of central banks.

Bitcoin appeals to tech-savvy libertarians , because it so far exists outside the institutional banking system and the control of governments. Bitcoin's appeal reaches from left wing critics, "who perceive the state and banking sector as representing the same elite interests, [ From Wikipedia, the free encyclopedia.
