minimum deposit $20, I don't know the minimum withdrawal, I want to make a withdrawal but can't because the bonus is still active, I have contacted them to cancel the bonus because I have made a second deposit so it is a barrier for me, usually how long will they respond?
You can use different currencies like XRP which only have 6xrp or 12$ as minimum deposit. AFAIK withdrawal amount is almost same the minimum deposit.
Maybe Bethog consider the ERC20 network as general minimum withdrawal for USDT sue to high network fee of that blockchain.
Although 20$ minimum deposit is just fine since you can’t enjoy the game properly with below that bankroll due to minimum bet on games is high already.
