There are many advantages to being part of a Superdarwin, even for the best darwins. If an investor chooses one of these darwins, he will probably also be able to include other good darwins in the same Superdarwin. If everyone wins, they can see their winnings increased (if they go up to 25%), or at least equal.
Sometimes, they will have to compensate the losses of their peers, and earn less or nothing, but at least have a chance to win something, since they will have investment, which today, not many have.
All darwins have drawdown periods, even the best. It is common for investors to sell in the valleys and buy in the peaks of equity, which does not benefit either the investor or darwin. The holding period will make investors more patient. And that they only have to pay if they win too.
