Therefore that 10% might stay and won't probably be out of that said site. Imagine that a site with the big name already enforced KYC means that the regulations on most crypto gambling sites are now strictly implemented.
I will think likely what happened to Binance right now, they used no KYC but they started to change the regulation and implement KYC for Binance. This may also happen to a certain casinos. ANd sadly, we may not have choice again besides doing the KYC if we have been familiar, comfortable, and enjoy enough gambling on certain casino platforms.
Actually, KYC itself is various, some may be too strict that also really need ourID photo and also our photo with the ID live video, but some may onlygive certai n email or ther data input.
But once they reach a certain size the governments and their different agencies begin to put their attention on them then they cannot get away with that behavior anymore, and they have no choice but to implement harsher and more strict policies regarding KYC.
