Bitcoin

The other day, I listened to the radio and heard about Bitcoin. And sometimes I read some articles about Bitcoin. Bitcoin is a digital currency that is not involved with any governments. Some Japanese guy invented the currency system. They say like gold, the amount of Bitcoin is limited and that's why it worth as much as gold. 

I can't understand well about Bitcoin because if I want to learn it I need high level math and computer knowledge. I wonder if I will use Bitcoin someday.
