I've heard Nitrogen Sports is a good online btc site for US sports, but was just curious if any knew of any others?
nitrogen is good , but you should go for bitcoinrush ( you need a VPN since you are in the US )
the reason for that is because bitcoinrush has a little bit higher odds and they have a reward system where you get money back on your bets
in general you should always shop for the best odds , so you need to check the different bookies constantly if you have a specific bet that you want to make
but yeah let's say 95% of the times bitcoinrush has the highest odds
