I think it depends on the perspective of the gamblers. I prefer having it later on. Not everyone is receiving a KYC request especially if they just only wants to play gambling games on a moderation like depositing small and withdrawing small amount of profits. I think most who are getting a KYC request from a casino are the one who are taking out big amounts of profits and those who wins because of promotions. As long as you don't have not doing a thing against their ToS, wins big or took a promotion, I don't think they will request a KYC from you. I'm sure there are people like me who likes doing small bets and just like enjoying a small time gambling. I believe those people don't get asked KYC too much and submitting it first before playing on a casino will surely be a hassle to them since we just want a leisure and not a hassle of submitting KYC.
Well, I know that many are very aware of everything that has to Do with KYC, but we must also understand that in casinos that are Reliable , I don't see that it is so bad to leave some kyc, of course, it is not that I agree With the kyc , never because my perception of this is very far from Going in favor of kyc, but seeing that companies cannot do anything and cannot function without that requirement, well sometimes I think that it does not cost Much, most new casinos All have that feature and seeing that they are so demanding to Remove it, casinos must Give explanations so that they can coexist.
