There's no question there are a lot of snake oil salesmen in this business. That said, there are a small number of elite traders out there that make these types of returns and are fully content not growing their account infinitely. Also, as your account gets larger, trading it for the same types of returns becomes more and more difficult just because of the position sizes you have to take. This reason alone is why the little guy still has a built in advantage over institutional traders who have to move around very large amounts of money to be worth it. I don't know if these guys are charlatans or not, but there are guys and gals doing similar things making similar returns consistently.
