sorry there must be, because at that time the expectation was that it would definitely rise even higher, but the reality was that it even fell in mid-2018. now it's too late to sell, now it has to be hodl.
Speculation and hype really drives the price high and we never know what really is the peak at that time. So basically we should have used stop loss in order to minimize the lose or maybe take some profit whenever the price drops drastically.
