I don't think many people bought bitcoin when it dropped below $20k because then fear prevailed rather than excitement. I remember when bitcoin fell below 20k$, many people kept waiting for bitcoin to fall below 15k$ to buy but in the end that didn't happen. I even know some people who believe bitcoin will fall below $30k again and they haven't bought anything so far. It can be said that not everyone believed and was brave enough to buy when bitcoin fell below 20k$ last year.
I also don't think we are still in a bear market, bear season is over and we are in a pre-bull phase, IMO. A target of $80k by the end of this year is not impossible, but I prefer the scenario of bitcoin reaching its ATH in 2025.
