One other thing, how are those withdrawals fees still standard. 4$ for a withdrawal.
Most of the time the reeal and used fee is much less but they always charge 0.0002 btc.
The withdrawal fee is a standard fee even exchangers has that btc fee, you have other cheaper altcoin options its even faster than waiting to wait for your bitcoin transaction to get confirmed.
I have always found it a bit weird to charge fix rate for every single withdrawal, that can't be reasonable is it? I mean if I have 10 dollars and want to withdraw that would mean 6 dollars to me and 4 dollars to stake, if I have 4 dollars, I can't even withdraw, obviously there is a minimum to withdraw but that idea makes no sense when someone who withdraws 10 thousand dollars also pays 4 dollars as well.
How can it be same for both of those people? Shouldn't it have some sort of situation where people do not pay fixed but depending on what their amount would required to have? That would be a lot smarter move because if a person withdraws 10 thousand dollars let them pay 10 dollars or more, while person with 10-20 dollars pays under a dollar to get their money, makes more sense.
Any withdrawal fee systems has its own advantage and disadvantage.
In this case fixed withdrawal fee will help you a lot when the mempool is congested and transacation fee jump up significantly.
If you play on a casino where the fee is based on the latest network situation then you have to pay higher fee than where you play on casino with fixed fee.
On the other side (normal situation), fixed withdrawal fee may cost you higher amount.
Anyway I have never known any bitcoin related services where the withdrawal fee is based on the amount you are going to withdraw.
