However, there are some scam casino who will use KYC as a tool to deny our payments. They will allow us to deposit without KYC but when it comes to withdraw they may ask for KYC and if the amount is big, they may deny the KYC without any reasons.
As for the withdrawal, I think many of them are still very flexible about it, if you are not the type that wins too much or withdraws a huge amount of money, grace may still cover you to delay the KYC, otherwise, it's good you prepare for the worst. Nevertheless, I learned from you today about more deposit than withdrawal plans of casinos, well, it's certainly an unfair practice and I don't believe any serious regulator will allow that. This is why they ensure that companies are well-capitalised before beginning operation, so there is no good reason for that practice in a sane clime.
There has always been a recommendation to only play in reputable casinos, and if this happens, we are lessening competition in the industry which will surely go against the gamblers. If we all continue to patronize the older casinos, how will the new ones survive.
Myself, i play primarily on Rollbit because I owe them that patronage. I don't encounter any problems with them. But I also like to spare small bucks on new casinos.
Back to the KYC issue, according to margkaisa, special validations are always in place when you win big. Infact, I learnt that some casinos will start asking for account statements and more.
