How expected growth depends on investor's leverage and player's bet


As you can see, normal investor gain profit on whales. 4x-leverage investor do not gain profit on whales.
On other side, 4x-leverage investor gain up to 4 times more than normal investor on non-whales.
So, leverage is a mechanism for investors to focusing investments on a specific type of players. Looks very clear.

RHavar, dooglus, is there any problems with such "real leverage" investments?
