I don’t see that KYC will be mandatory. Casino that have a license was already regulated which don’t required KYC. Only the amount of bet in Slot was being discussed to be regulated to control addiction of the player, This will be beneficial to the players because they can play without worrying about big loss. Actually this not a big deal because if ever the player reach the 100$ cap per month then they can just play other gambling games like dice, sportsbet and card games.
I think the KYC can be applied in the casino based on fiat, but in the casino based on crypto, that won't be easy because it needs regulation from the government, and many countries still not accept crypto. Perhaps, slots can attract many gamblers to spend much money in the games because to gamble on that game will no need to use big money in one bet. But I think all gambling games should be regulated because if only one gambling game regulated, people can still use the other gambling games to gamble, and there is a chance to see another addiction from other people. I think $100 per month will be too big to gamble for one person, but that can happen to the addiction gamblers because he can use more money to gamble, so he thinks that he can have more chances to win.
