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 do not, all investors will immediately buy when the market falls. they will see why the fall happened, if it will have a long impact I think investors will also think of holding their money first even though prices are cheap. but if the market still moves up even though a little of it can make investors interested in assets that are cheap.
