2.There is a reason why casinos would want to avoid crypto. First, the legal ones will have to arrange rules in accordance with certain countries, and, if cryptocurrencies are banned there, there’s a high chance that the casino itself will lose a whole geographic sector due to that.
Second, casinos benefit from knowing their customers in the face, so to say, they offer bonuses, give special treatment, try to make sure that the client will remain loyal. And, in addition, reduce cheating by requiring KYC. Needless to say, with the full adoption of crypto and the idea of anonymity, all of that will be harder.
