If they can add Litecoin and Withdraw via USDT Bep20, then those will go with very low fees.
Litecoin?
LTC is already available on bet105, but
litecoinit has nothing to do with USDT. Note that the BEP20 you are talking about is under binance smart chain.
Most of the popular casinos already have these options to make it easier for their customers because $2 is such a big money that can earn you several spins in slot game.
I feel you misunderstood Pmalek's post.
As I already said in my previous posts, I requested a USDT withdrawal on ethereum network (which is the only available option for USDT withdrawals on bet105) a few days ago and I wasn't charged any fees for that.
