The problem of those prop firms, is that they offer fixed payouts split percentages in exchange with floating incoming fees from bought challenges. That can only work, as long as the floating income stream of fees does not abrupt goes down. Or they need to pay any payouts from their pockets, which can only work for some limited time. Then they start to play dirty tricks with hidden rules and being scamartists to deny any (bigger) payouts. If they had floating payouts as well but lower than their floating income from fees, then this would be longterm stable business. My opinion.
