I don't worry too much about withdraw fees on crypto casinos because I only deposit! House edge, fairness of the games, trustworthiness of the sites are higher on my list.
But yes... some of these withdrawal fees are ridic.
The fact that you mention that the fees for withdrawing is ridiculous means that you worry about it. House edge is pretty much out of control of the players and most gambling houses and sites have close to same edges. Fairness and trustworthiness is a must since gambling on a rigged game is pretty frustrating.
