Welcome here. Your site looks cool. and it is really interesting that Only 100 Satoshi deposits and withdrawals can be made here. However, I do not understand how much the fee will be deducted if someone withdraws 100 satoshi. Where 100 Satoshi value only $0.02. Which is less than the transaction fee of any crypto network. It keeps me in confusion

Maybe there are more technicalities involved in integration or it is not yet popular among the gambling houses. Macaw.casino will set the trend I guess.
