Isn't investing in a bankroll the equivalent of gambling? Because if investors have to carry lose then most likely it's also a gamble. However, usually house always win more than glambers and that's how they continue their business. I have seen couple to casino who are giving opportunities to invest on bankroll and a return a percentage from their total house edge. I didn't invested on such as platform. But if the platform is trusted enough then it would be a passive income for lazy people like me. So most important thing is how trusted your investing casino.
