It will be good for the members if they do not have to fills KYC, although they are on the limit by your rule. I am sure they will not try to break the rule because they can make their account banned or blocked. The member non-KYC will play as usual like in the other gambling site and obey the rule.
I already register on your site and see what is inside. I see the minimal deposit is about 0.0002 btc so I think that will be enough for the member to check the site.
Maybe you are right or you are wrong, if the business has to comply somehow to regulations then KYC is inevitable but if they force it even though it's not really needed then they are wrong but given how online gambling is getting regulated, I think KYC is the best course of action. Their minimum deposit is pretty good, I might check it out later.
