I do not think bitcoin can fall below $15500 again. It may go to $16000 or $17000, but what we look up to now is all-time-high. Bitcoin will be more than $100000 one day. Do you know how profitable institutional like Microstrategy would be by that time.
The market does not rely on your thinking for its movements. In fact the market usually moves oppositely to what is thought by majority of the crowd. I can not say will Bitcoin falls to under $20,000 or $16,000 but you should not exclude that possibility.
At least let's check the chart and price history. Not too far, in the past bear market and shortly before a 2020 bull run, when most of the crowd thought $7,000 is likely a bottom range for Bitcoin and believed from that it will start its bull run after 2020 halving.
What happened? It crashed almost half to below $4,000 as a last massive kill before a V-shaped recovery and started its new bull run.
Will it repeat in 2024? You judge it.
