Where does bitcoin came from? How it's made and how does it expand/grow? Thank you for any answers.
Its a worldwide cryptocurrency with digital payment system. I heard its created in 2009 and the creator name was Satoshi Nakamoto who belongs to japan. Nobody's know where this guy is maybe he is hidden somewhere.
Its a reward gaining with the help of mining. Most of people exchange it with each other currencies and trade it with altcoins.
