A few members of this community, if not most, always perceive crash or dip as a negative thing. Well, for some it can be a negative thing, but for many others that understood well how this market behaves, perceive crash or dip as an opportunity to buy and invest in many altcoins with high potential.
On another note, many others don't have the resources to invest, but just hold on to your coins and never ever sell your assets lower than the buying price.
