i find rollover to be more than most casino. every other casino have rollover 35x but you have 50x why is that?
Do you even have to ask? to make sure that less people will be able to complete the rollover. Unless you are very lucky with your roll, most people will not be able to complete the rollover and will end up losing their original deposits as well. The higher the rollover , the lesser the chance for people to complete it , its logic
This kind of deposit bonus with high rollover requirement is not interesting anymore in this bitcoin gambling industry imo. Smart gambler will never claim this bonus, because their deposit will be locked till they complete the rollover and mostly they will lose all their money as you said.
