I've always held unto this principle. If you think the thing you're investing in has real value and you're in it for the long-haul, then market crashes and rebounds shouldn't matter too much. Imagine 5 years from now when any major crypto could be worth much more, for example litecoin could be 23,000 instead of 230, would this market drop still matter? Of course not. That's why I fully agree with you and think people should stay calm. In doesn't matter. Years from now, all of these coins will be worth many times more than they do today.
