Hi @stepdadbam, basically Bitcoin is a digital currency that you can buy on an exchange or earn through a process called mining. The great thing about it is that it is decentralized meaning not you or I or any single entity can control it. And it has a fixed supply of 21 million coins so it can't inflate like our fiat money (dollar or euro). I'm curious as to how you know about STEEM but have not heard of Bitcoin?
