So I downloaded the app as i was thinking of buy some bitcoin which made me think, "if i buy say, $100 worth of bitcoin with a credit card (or wtv) where does the bitcoin come from? Who's providing it?"
Especially if blockchain.info is just a wallet.
Anyone know?
If it's a company, they have reserves as bitcoin. If it's an Exchange, there are pairs, peer to peer type, and you buy. This means another person sold that bitcoins to you.
