Maybe I'm missing it before, look like the website was updated with a new payment method with the Binance chain

Yes, we know the Binance chain is one way we can reduce the fee, I hope they could hear another suggestion from members here such as Doge, LTC, And more. and also reduce the minimum deposit such as $10 or under.
USDT fee on binance smart chain is really low compared to the ERC-20 one. I think OP should consider about reducing the minimum deposit amount now. And adding such coin like ltc, doge, trx is obvious to get some real crypto gamblers at the site. Btc and eth is id must needed as well. Maybe GolfCasino will add more coins because still there is other crypto logo in payment method. Though I couldn't find the information about other coins minimum deposit and withdrawal limit anywhere now, seems like they have updated the FAQ page.
