Umm. So if a gambling site is only dealing with bitcoins or altcoins and not fiat involved, is KYC even required? And which countries mandate that? Perhaps gambling sites should incorporate in a country that doesnt have KYC required instead.
I think you need to read the thread once again to understand this topic.
Crypto gambling sites will not ask for KYC as a default but if you deposit a huge amount then they may ask while withdrawing funds and they never list any particular country but they can block withdrawals if they suspect your deposits. So to avoid these issue may consider playing with smaller amount deposits then your account may be safe.
