For USDT withdrawals, they only support ERC20 network.
By the way, the transaction fee on ETH network isn't really expensive these days.
If you check the ethereum blockchain, you will see that USDT transactions are being confirmed with the fee of around 0.0001 ETH. I remember ERC20 transactions were much more expensive in the past.
Yes, you are right but most people still think that ETH fee are high and they avoid using ETH blockchain especially if we compare it with other chains. Anyways, bet105 should also give the option of Bep20 and TRX blockchain for withdrawals. Also, when we compare the different chains, BEP-20 transfers are almost free unless the sites themselves set some withdrawal fees in order to cover the maintenance costs.
That's what I was thinking too—that the fee on ERC20 is high. For a 0.001 ETH transaction, about how much fee would be deducted? The thing is, when I gamble at a casino, I usually use TRX, BEP20, SOL, and POL as my deposit network.
But I really use BEP20 most often because it truly is cheap. However, if the fee were low even on the ETH network, that would be okay too,
because the lowest I've seen is around $2 or $3, if I'm not mistaken.
