As investors staying calm during bitcoin bear market rewards a lot. Some investors are afraid of bear market, they can't endure it because they feel their money will be gone, so they listing to the noise, and begin to sell in panic, but they end up loosing all the profit that the market will later bring.
This words are conflicting, perhaps, you didn't know how to blend it well. As good as it's encouraging to keep your Bitcoin investment forever, don't forget that many people also openly regret keeping it longer. Not that Bitcoin will not be edging higher over time, but seeing their thousands of dollars profit slipping back to losses or to almost nothing is, indeed, disheartening. For this, the right action at the right time and price reasonably weighs more and smarter than believing keeping your Bitcoin all the time is the best shot. There's always a room for reaccumulation at a more favourable price, instead of seeing your profit slipping away from you in multiples.
