What happens is that KYC is a double-edged sword, sometimes they can sell it as a security measure, but if we dig deeper, it is known that it is not like that, it is simply a shameless technique to extract information, well obviously one like normal player who does not make such big bets, because I think that a thief or a scammer would waste time, in fact he would spend more time and resources than what he can obtain, on the other hand, big players, those who move more than 10btc, do not care He likes to leave his kyc and for obvious reasons, as I said before, you can leave kyc in your favorite casinos, but not in all of them, and I know that each player should have a maximum of 10 favorite casinos, mostly they should be less, due to the issue of loyalty.
Only bad platforms will sell KYC documents of their users to get money for their benefit. Good platforms won't do that because it is harmful for their reputation which can cause to loss in their customers. When reputation is damaged with such bad activities, it's very hard to get it back.
However it is not only risk with KYC because even if a platform is trustworthy and keep up their promise on protection for their customers KYC documents, their security system and data base can be exploited. From such exploitation, many things can happen after that including KYC data leak.
So KYC is good or bad, acceptable or unacceptable, it depends on each person. It's just sometimes a business company does not have choice to request KYC on users because they have comply with local laws.
