A great poker room is PmPoker, the only flaw of this Room is that few players unfortunately 
Great ?
I just now register in this room I can't see even 1 player 
It is obvious that ImFire is that site's shill or owner, no one plays there, I just ignore that site. That site owner is a bragger, he estimated his no one plays site for 4000btc, and he wanna sell 30% share, that's 1000btc, what a greedy admin.

For good poker sites, I recommend SWC, betcoin.ag, luckyflop.eu are the best ones. There are some new sites are good: bitcoinpoker.gg, allincrypto, cryptopoker.
