every gambling site has an address that should be easily detected by a transaction. as far I know, the address marks the name of the gambling site at the end.
From this situation, the user must use a non-custodial wallet like electrum to transfer funds from a gambling site to exchange.
That is the best solution for a gambler so they do not have to face that problem. But I suggest using a multi-wallet with a conversion feature to send and receive the coins because with using multi-wallet, we can convert the coin to another coin and then send it into the exchanges if we want to sell the coins. That will help us to solve the problem without causing the other problems
