Well, there are many to choose from. Different people have different preferences.
I'm guessing OP is looking for what I've been dying to find..the most all around well established sports book that deals in BTC (or other crypto).
Sooo many things weed out the majority of them. Is casino legally licensed? What are mins, max bets, what are min and max withdraws, what sports are offered, customer service 24/7..or even good at all? on and on.
And how is that not Nitrogen Sports? They offer the best odds and have proven to be the most trusted sports betting site.
And do Bitcoin gambling sites have to be licensed? I'm aware that that it makes them more trustworthy, but it won't really stop them from stealing our money if that was really their intent.
Btw, licenses are a joke. Read up on the Fulltilt Poker scam.
