Wow, there's a lot of them already, glad to see nitrogensports still on top, I used to bet on that site and no issued encountered.
You are missing coinbet24, they offer both anonymous registration only with Bitcoin and they ask you for KYC/AML when you want to play in FIAT currencies with them.
Yeah, I agree OP miss this site, they have a good site also although odds are not really competitive but the good thing is they have live games and no withdrawal fee every time you transfer from your account.
They have no withdrawal fees if you always withdraw more than 10 mBTC (0.01 BTC) but if you withdraw lower than this amount then there is a standard fee of 0.7 mBTC (0.0007 BTC) for each withdrawal. They may not have very competitive odds but they are almost the same as Sportsbet when you compare their betting line options, tons of betting line options here too.
