Given the current events and the number of investors in BTC, I don't think it can fall back to $50k; it's unlikely. In fact, large institutions might take advantage of the situation to buy BTC cheaper, but the only way that could happen, as I see it, is if very devastating events occur in the world, causing fear among large investors. I know that would cause the price to drop significantly, but based on price action alone, I don't see it as possible.
Honestly, when bitcoin hit $126k, did you think it would drop below $80k or $60k? If I recall correctly, quite a few people were also firmly convinced that it couldn't happen. They also believe that institution will step in to buy if prices fall, so the likelihood of a sharp decline is considered low. But what happened? Bitcoin fell to $57k in June.
I don't know whether it will drop to $50k, but as long as the bear market isnt over, we shouldnt rule out that possibility. Bitcoin is currently at $63k, and if it drop to $50k, that would only be a 20% decline. That's entirely possible.
