Agree to that, there are gamblers who are looking for this kind of options. The fact that fees are really hurting gamblers bankroll, they'll be enjoying this kind of set up where they can switch to another coin when they are in the process of withdrawing their funds, same with depositing, if the gambler wanted to extend their stay, with coinswitch, they can simply trade their deposit coin to whatever alt and use it for longer stay.
Some are using strategy that's needed a much deeper bankroll, it can applied using much cheaper coin with same patterns. But same with your last statement, It will be on the owner's side to whether to add this feature or continue from how they setup their platform.
