It all depends in what state you live.
For example New York is very restrictive for all kind of crypto and betting related websites.
I am not 100% sure but you can check out betonline.ag website.
They accept Bitcoin and people from United States.

If OP still need then as stated above just one good and solid option is betcoin.ag as its one of best sportsbetting site here in bitcoin and altcoins community with long history and good reputation they never ask for KYC just in case something very fishy happen no other site is going like them right now for USA based customers.
