Many people claim that they will buy massively and not look at the price if Bitcoin drops below $10k, $5k or $3k but I bet if Bitcoin drops to $3k, people will run away in panic. No one will believe in the bitcoin revolution or the financial freedom that bitcoin brings anymore.
Just in the past few days, the price of bitcoin suddenly dropped to $83k and the fear and greed index dropped to 10, which shows that the market is in extreme panic. So if bitcoin continues to fall and goes below $10k, I don't think many people will stay in the market, let alone buy as much as they can.
But that's just a hypothesis, I don't believe that will happen.

What happened to all those predictions of $350,000 in 2025?

If I remember correctly this prediction was made by Robert Kiyosaki and many people agree with him. But with the recent movements of bitcoin, perhaps many people have started to doubt it.
Fear and Greed index <20 at a price of >80k. What more do you want? Look at the historical fear and greed index, we are bound to go up again.
