Poker requires skill, concentration, and luck. These are all integral parts of the game. For this reason, online poker is not the most popular game. Crypto casinos don't have enough players
Basically, that's the reason why it's hard to gain poker players in a crypto casino.
Unless, the casino has long been operating and they already gained patrons for this game.
And they just come and go. But for a new crypto gambling site with poker on their list, hard to attract players.
It will take time to gain good number of regular poker players.
And the problem is, a lot of them are tired of waiting fellow poker players on the table so they just move on.
