I've always thought that if Bitcoin was ever to hit below 3k again, we'd be fucked, I reckon a lot of people would pull out and completely give up on it (except the enthusiastic one).
No, It's not gonna happen, either btc will hit $3k or below again or people walking away from crypto market. Either of the both won't gonna happen. Let's say the price of btc is back down again at $3k I dont think people would turn their back away from accumulating more btc. People today is becoming smarter learning from their past mistakes. Btc wont just easily die, not atleast all of the pieces are mined or it might become stable. We never know.
