Bitcoin isn’t owned by anyone. Think of it like email. Anyone can use it, but there isn’t a single company that is in charge of it. Bitcoin transactions are irreversible. This means that no one, including banks, or governments can block you from sending or receiving bitcoins with anyone else, anywhere in the world. With this freedom comes the great responsibility of not having any central authority to complain to if something goes wrong. Just like physical cash, don’t let strangers hold your bitcoins for you, and don’t send them to untrustworthy people on the internet.
