We've doubled the gas fee without increasing the withdrawal fee on the site, hopefully it will solve the long confirmation issue. Sorry for the delay @hopenotlate
Ethereum is already something that is cheap and very fast, I do not think that you could really spend too much to actually withdraw.
Nowadays if you spend something like 20 cents per withdraw that is more than enough, and if you are not gambling on a price that makes 20 cents very small I am sorry but maybe you are not playing with enough money to actually justify gambling.
Normally the minimum people play with is 10 bucks and definitely a lot more, when you are gambling with at least 10 dollars or more 20 cents will be very cheap and if you are playing under 10 dollars you are going to get 20 cents felt but it really doesn't justify gambling, that is more like faucet gambling. This is why I think a fixed fee would be fine as long as it is decent.
It is not about how much you pay versus how much you play with. I could have a million dollars but if I am paying 1 dollar for something that worths 10 cents, that is still not a nice feeling, why would I be fine with getting robbed when I could pay less, just because I am rich doesn't give people the right to charge me more for something I could pay less for.
I am nowhere rich at all so it hurts even more because I am doing this small time and I do not like to spend too much money on something I do not need to. Plus you are thinking about individual gambler based, but the reality is this place has a lot of people gamble and withdraw, so yeah it doesn't hurt one person but when you combine ALL the fee's that is paying, that comes to a lot of money.
