As of now, it is best to avoid using Roobet's withdrawal feature until charges are taken into consideration.
If players want to use Roobet as a casino where they play, then of course they use the withdrawal feature, especially if they can make their balance increase because of winning, if withdrawal fees are an obstacle then you can choose LTC as a deposit option so you can make withdrawals with LTC, since the fee cheap compared to BTC or ETH and ETH is lower than BTC, however lowering the BTC withdrawal fee is sure to be greatly appreciated and pleasant thing for players with low balance like me.
Small gamblers will certainly choose the lowest option if there is LTC in a situation like this so I'm sure there will be more small gamblers using LTC as deposits and withdrawals, not much if the balance does increase because winning says not too big then that can still be with withdrawals LTC, so indeed looking for something to avoid larger drawdowns.
ETH gas is rising I don't know how much ETH withdrawal will be charged at roobet? Is it over $4 or more?
