I have played at Carbon Poker, Lock Poker, Full Flush (no longer operational), ACR, BCP, True Poker, Bet Online,
juicy stakes and Ignition. I've never deposited successfully onto ACR though...(only played with winnings from their
freerolls). And I've only withdrawn from one of them....the only one I still mess with.....Ignition.
For me Ignition is easily the best choice. They have decent player traffic and I like that all of their MTT's are freezeouts. (No add-on or rebuy tournaments.) I also like that the tables are anonymous. (I'm not using a HUD). So I feel like that helps to level the field.
They pay very fast via the Bitcoin method. (like 8 hours.) and if you sign up for a
visa bitpay card then you can get it transferred to USD immediately, BUT, the major drawback of this is that Bitpay doesn't currently support withdrawal from ATM or cashback of ANY kind. Meaning you can shop online or at the store with your card, but if you need cash you're S.O.L. (pretty jacked up huh?)
Frankly...The only one's I would trust with my money are ACR, Bet Online and Ignition.
