Why I should be afraid? If crypto falls, the price will become more interesting for big whales which will do everything to pump it back after they buy at cheap price. So no matter what happen rich people become more rich because retail investors are afraid buying for cheap, they are buying only when price is too high. 
I agree with you, if the price falls again, it can grow back very quickly, this has already happened this year and if it happens again, this is another chance to earn quickly, so there is nothing to fear in any event
