I think the problem is when KYC is required only when the user tries to withdrawal the money
Personally, i dont mind if I deposit the funds and the support says something like "Your AML score is high. Please, do KYC or we will send your funds back to the same address".
But taking the funds hostage and demanding KYC is quite unfair.
BUt I don't know any cases of similar situations which happened in betfury.
It would be beneficial if centralized platforms provided advanced warnings about this.
However, I think Betfury, other gambling platforms, or centralized platforms may use different services to determine the AML score. In other words, one service may indicate that a user's deposit has a low AML risk score, while another service may indicate that the same cryptocurrency may have a medium or even high AML risk score.
a few hundred of either you will likely not have to worry.
