I've read that some services like Coinbase will shutdown your account if they even suspect you are buying bitcoin to use at a casino or sportsbook. I don't really need that kind of stress so I was wondering if there are any websites out there that sell bitcoin to U.S. citizens who don't care what you do with your crypto-currency? I thought bitcoin was supposed to be anonymous anyway so I don't know how companies like coinbase can track what you do.
