SwCPoker.eu is the site that continued from Seals With Clubs, the largest original Bitcoin poker room, when it shut down in 2015 due to government pressure. At that time the room lost a significant portion of its traffic, but in November 2018 the site came back with 100% new software that players have reviewed favorably.
Bitcoin Poker 3.0 has brought back many of the old players and lots of new faces that didn’t play the original version. The new SwC Poker is still Bitcoin only for deposits, play, and cashouts.
Withdrawals are fast, often averaging only a few hours, although the site asks for up to 24 hours to manually process them. SwC Poker says they check for collusion and team play.
Taking into account the anonymous games and transactions, the site is often referred to as the Wild West of online poker.
