Feel free to add any similar experiences you've had (maybe with funds coming from poker sites - as your name suggests) and I can add them to the OP! I know some exchanges and other services complain about funds from gambling sites, but don't know exactly which ones, so any feedback in this direction from a long-time forum member would definitely be appreciated.
In my case I have not had any problems with crypto gambling sites and as I have said in other threads, I play poker on fiat sites because there is much more traffic and better software, besides you can use statistics software (legal). The problem with crypto poker sites is that if they are without KYC it is easy for several players to collude. In other words, privacy makes it easier to cheat.
From what I know about gambling sites there is a trend that is the same as what we are discussing in the thread. Years ago practically no gambling site required KYC. Nowadays there are a few left but less and less, so the trend in the future is going to be like that. If we want to defend privacy we should defend the gambling sites without KYC, and only play in them. But the fact is that privacy has been lost in gambling and the use of crypto gambling sites does not seem to have decreased.
