What do you think - if RooBet ever adds BEP-20 network to its system, will it be possible to solve this problem?
What I think about adding BSC network to solve the case? I doubt it. And for what I knew about Roobet, they will stick to the coins and network that are the most used and they probably want to just stick to few coins and network for deposits and withdrawals to eliminate some potential problem caused by too much payment method. Plus we do not know how much adding another ETH network will cost them, it might need some time, effort, and additional budget.
Therefore, I think adding a new network does not weigh the same with the problem which you have personally caused in the first place.
On the other hand, if ever Roobet decided to add new ETH network, which I doubt, "Will it solve the problem?" Definitely yes.
