Bitcoins are controlled by a network of users who control and verify the monetary transactions. Making a bitcoin payment is as simple as sending an email. Basically, you transfer bitcoins from your digital wallet, which you obtain when you buy the currency from a crypto exchange to someone else's digital wallet using an app or website and the person's unique bitcoin address. It's really easy. It's really just a matter of tapping on your phone or pressing some buttons on your computer. And of course, these transactions are not controlled by a bank or a government, and they can be performed anonymously, which is a great advantage, but also a disadvantage in many ways. Lastly, a blockchain is a chain of blocks that contain information. The bitcoin blockchain, for example, stores details about the bitcoin transactions, such as the sender, the receiver, and the amount of coins they're being transferred.
