The physical Bitcoins you see in photos are a novelty. 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.

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.
