No double fee brother.
"Minimum deposit is 50USDT" means total money you will send to casino. (ERC-20 chain will charge you 20$) then your balance will 30USDT.
when you want to withdrawn, minimum withdrawn is 50USDT, casino will pay fee. you will receive full 50USDT.
if you balance is under 50USDT, you can play casino/or deposit more to have at least 50USDT to withdrawn.
It's clear ?
this 10USDT is only for new player w/ 1st deposit brother.
I understand your concern. That is why we have to request a minimum withdrawal amount of 50USDT. Also, when we open a casino we have to prepare enough money to run it. If you have free time, hope you will experience GolfCasino and give us feedback on this Bitcointalk.Org forum topic.
Sincerely thank
we will get 40 dollars not 30 because of the $10 depoait bonus but its crystal clear to me now .
thanks for explaining it again

and i like to say that you are generous because you shoulder the fee . now my concern is towards you .
arent you going to loose this way ? if more and more gamblers will win and withdraw .
