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.
