Everyone here is talking about Pokerstars...
And I have to admit that I am yet to find a BTC accepting site that is reliable.
Most of them are either proved scams like betcoin or really poorly made gambling site like Nitrogen...
You can check the website OP mentioned (swc poker), there are freerolls every hour so you can check out the tables before depositing.
It looks like a small little community of regs, but then again it's always the case anywhere you go where there isn't a lot of people.
