It can be found if we can look for it carefully because with so many casinos nowadays, not all casinos will allow gamblers not to do KYC. Casinos today are different than they were a few years ago, and with government interference, they have to keep up if they want to continue doing business. And if we have found a casino that really can be trusted, we should also be able to be calm about doing KYC because the casino will try to protect the important data of its customers.
Most of the casinos do look at what country you are from and base their regulations on their judgment as to whether they will require you to undergo KYC or not. I have friends who are into sports betting or gambling in casinos, but they are not required to go through KYC, just like me. Therefore, we enjoy the full liberty of gambling anonymously.
