Sad but true. When the price is down, few people are interested in buying bitcoins. But in a hype and with high prices, people suddenly become interested in bitcoin and buy him dearly.

I've experienced this again and again in the last few years in my circle of acquaintances and it hasn't changed to this day. I wonder when will people finally learn it?

I think it has something to do with human psychology. Whenever something drops in value suddenly, there is a panic that its become a dangerous investment. This is very understandable. I mean look at what happened to LUNA. Anyone who got out in time was lucky to have done so. So in such cases, being suspicious of the dump was the right thing to do. But then again the crash was due to the shitcoin itself that collapsed. Not because of short term FUD.
But when it comes to Bitcoin FUD based dips (like right now with the entire FTX and seized 50k Bitcoin drama), we have learned not to sell on such news because in the long run, it does not affect the value of Bitcoin at all. Its still going up. So every FUD dip should be seen as a discount price.
