The people who buy in rallies and sell during bear markets and then don't believe in bitcoin anymore are clowns. If the price went to 25k in the next few months I guarantee it that the community will double maybe even quadruple in just a few days.
I don't think that the people who are selling during bear markets and those who do not believe in bitcoin anymore are clowns. Maybe they have their own personal reason that even if they wanted to continue, they just can't due to their reason. Especially those people who sells at bear market, maybe they can't take it to see their investment falling which is instead of making a profit, they got loss.
