Why are you just now wanting to learn Bitcoin, where have you been all this time, Bitcoin has almost been running for 14 years, but it's good if you want to learn it.
Are you serious about wanting to bet on gambling especially 'poker' if you like you can see in the thread below.
Topic: Withdrawal Fees and Withdrawal Amounts on Crypto CasinosThere you will find gambling sites that offer trusted poker rooms, either here or outside, you just look there and choose 1-5 gambling sites that offer top poker bets.
From the sites listed on the suggested thread, which sites are offering poker room that he is looking for? I can not find even a single site that provides poker room on that thread. The thread is also focusing in giving information related to withdrawal, no specific information about the provide games by each site. It will make him confuse because he is new to this forum.
@Saterday_to_da_moon: Not many sites provide poker rooms, only few are existing and running with good traffic such as SWCpoker. It is one of the oldest and the most reputable bitcoin poker sites you may check and try. Good luck.
