They would be worthless without the private codes printed inside them. Each Bitcoin is basically a computer file which is stored in a 'digital wallet' app on a smartphone or computer. People can send Bitcoins or part of one to your digital wallet, and you can send Bitcoins to other people.
Every single transaction is recorded in a public list called the blockchain. This makes it possible to trace the history of Bitcoins to stop people from spending coins they do not own, making copies or undo-ing transactions. There are three main ways people get Bitcoins. In order for the Bitcoin system to work, people can make their computer process transactions for everybody.
The computers are made to work out incredibly difficult sums. Occasionally they are rewarded with a Bitcoin for the owner to keep. People set up powerful computers just to try and get Bitcoins. This is called mining. But the sums are becoming more and more difficult to stop too many Bitcoins being generated. If you started mining now it could be years before you got a single Bitcoin. You could end up spending more money on electricity for your computer than the Bitcoin would be worth.
There are lots of things other than money which we consider valuable like gold and diamonds. The Aztecs used cocoa beans as money! Bitcoins are valuable because people are willing to exchange them for real goods and services, and even cash.
Some people like the fact that Bitcoin is not controlled by the government or banks. People can also spend their Bitcoins fairly anonymously. Although all transactions are recorded, nobody would know which 'account number' was yours unless you told them. In an online chat with social media users in January , the world's richest man, Elon Musk, said he was a big supporter of Bitcoin.
He even went as far as to change his Twitter bio to " bitcoin". He has repeatedly shown his support to online currencies in recent years and caused major movements in their values due to his own personal wealth and influence.
This particular endorsement led to the value of Bitcoin to rise significantly. Every transaction is recorded publicly so it's very difficult to copy Bitcoins, make fake ones or spend ones you don't own. It is possible to lose your Bitcoin wallet or delete your Bitcoins and lose them forever.
There have also been thefts from websites that let you store your Bitcoins remotely. The value of Bitcoins has gone up and down over the years since it was created in and some people don't think it's safe to turn your 'real' money into Bitcoins. He said that he was "very nervous" about people using Bitcoin for payments pointing out that investors should realise its price is extremely volatile. By this, he meant that the value could drop significantly at any moment and investors could lose a lot of money.
Elon Musk becomes richest person in the world. These comments are now closed. Trump impeachment trial will go ahead after vote. Bitcoin makes it possible to transfer value anywhere in a very easy way and it allows you to be in control of your money. Such great features also come with great security concerns. At the same time, Bitcoin can provide very high levels of security if used correctly. Always remember that it is your responsibility to adopt good practices in order to protect your money.

Consequently, keeping your savings with Bitcoin is not recommended at this point. Bitcoin should be seen like a high risk asset, and you should never store money that you cannot afford to lose with Bitcoin.
If you receive payments with Bitcoin, many service providers can convert them to your local currency. A Bitcoin transaction cannot be reversed, it can only be refunded by the person receiving the funds. This means you should take care to do business with people and organizations you know and trust, or who have an established reputation. For their part, businesses need to keep track of the payment requests they are displaying to their customers.
Bitcoin can detect typos and usually won't let you send money to an invalid address by mistake, but it's best to have controls in place for additional safety and redundancy. Additional services might exist in the future to provide more choice and protection for both businesses and consumers. Some effort is required to protect your privacy with Bitcoin. All Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address.
However, the identity of the user behind an address remains unknown until information is revealed during a purchase or in other circumstances. This is one reason why Bitcoin addresses should only be used once. Always remember that it is your responsibility to adopt good practices in order to protect your privacy.
