To be honest the best thing you can do if you want to play poker and earn a reasonable amount with it, is to stick with fiat currency platforms. There are several platforms out there in the fiat currency world with several thousand, even tens of thousands, of concurrent players at any one time. The wider the pool of players, the more likely you are to be higher in the skill ranking and be able to make some sort of profit from this game. If you go to SWC, probably the most well known crypto site, you might be playing against 150 people at times - they might each have years of experience and you are literally playing in a pool of sharks who do this full time and are ready to grind away your money. Unless you are absolutely top tier, you will eventually leak it all to them.
