No. There are lots of sites already with this feature but no one till now got success or make big profits out from investing in a site's bankroll.

This is not a sure win even a house always wins. There are whales at each site and there is always a possibility that someone will get big winnings. Because that is the common scenario at any site, instead of continuous profits by the investors, their balance is just playing and swinging in a specific range.

And this is not easy as others think. There is a big investment needed even just for 1% of the total bankroll. This can't be afford by a normal users.
