This is what I don't like, if they are not supporting bsc then the transaction should not go through so that such mistake will not happen. Is it that the blockchain needs more advanced developmental system? The blockchain developers should improve on this to avoid sending funds to another network. I did a similar transaction in Ton network. Now in Ton network, their is a memo tag code which you have to add when you are sending to the receiver's address. But didn't notice it because it was not added at the initial time and I made the transaction, it went successfully but I didn't receive it. So I have to chat up the two parties involved and for weeks the funds were reversed to me. But I don't know that can happen here since this is casino and they are saying that they don't accept BSC network and that is your funds are gone because they can't do anything to reverse them since they themselves don't operate with the particular network. But if they are using the address, they suppose have the network. Let them do things in fear way.
Yeah that's little off for that situation since for sure there's situation that we might create a mistake for sending those funds on wrong network and they should have proper solution to help their costumers. But what can we do right? if they have clear warning that they are not supporting other side networks that's why the only thing we could do is to be more careful sending our funds using BSC since so that we will not commit the same mistake made by the compromised gambler.
Maybe if lots of people will encounter this kind of issue maybe they will find a good solution for this issue. But since this is rare situation I guess they will just give a warning and that's it.
