A number of major U.S. online bookmakers like 5Dimes, Bovada and BetOnline now supports bitcoin. The problem is that these regular internet bookmakers still require you to go through a Know Your Customer (KYC) procedure. This means that even if you use bitcoin you still can't remain anonymous, which is probably the biggest advantage of gambling with bitcoin, especially if you American. As a result, new online sportsbooks have appeared that only accept bitcoin and completely protect their players anonymity. CloudBet, mBit and BetCoin all offer anonymous sports betting although Nitrogen Sports has quickly become the number 1 bitcoin sports betting site from U.S. gamblers.
