There is a way, and some casinos have already implemented dynamic fees that take into account the current state of unconfirmed transactions in the mempool and change the required fees accordingly. In some other places, players are given a choice between a faster or slower confirmation time. Other platforms have static fees and you pay the same amount no matter the conditions on the blockchain.
Good to know that there are progressive casinos that do that and I find the static fee the least attractive of the bunch unless it is defaulted at a really low amount then I don't have a problem with that. I plan to gamble when I have enough money to spend on it without any worries so I was concerned with fees and stuffs.
