If it's not less than the amount they are paying, then why have the rule?
I don't follow what you're saying here. The rule isn't for the would-be launderers. The rule is for the casino.
A couple years back I asked one particular casino about why they had that rule and they said it was one of the requirements according to the terms of their license, which was a Curacao license. I looked for the correspondence but I must have deleted it long ago.
A few BTC-based casinos did not have a rollover requirement...
Such as...? Or you mean they didn't in the past and don't exist anymore...
Anyway, we're pretty off-topic now. And these 2 users blatantly ignore whatever was discussed prior to their messages and post some nonsense about soccer/football:
Meh, just looks like people trying to continue conversation that is normal for that thread. They probably put the accusers on ignore.
