Sorry to ask, but is this other place (I assume it's a casino) licensed!? Because as far as I know any regulated and licensed business has to declare and report transactions above a certain threshold (depending on the license provider and the county where the casino operates).
The good thing about Roobet, though, is that they ask for kyc (level-1) from the moment you create an account and don't wait till you make a withdrawal request as many other casinos do.
This isn't true. There are many anonymous crypto casinos out there that don't require KYC at any point of time and I can attest to that thanks to my experience with some of them over the years.
Some of these sites never ask for KYC even if you won a million bucks(Unless you cheated) while some others force customers to provide KYC in order to retrieve their winnings.
I agree. They casinos will require you to pass some KYC documents when you cheated, or if your transactions on the casino including the deposits, withdrawal, and any bets are heavily suspicious. I do not know exactly how can the track it but I believe they have the tools that are needed for that matter.
Some casino even not regulated forced you to pass a KYC in order for you to be able to withdraw.
