Why do people always think about trying to catch the bottom, even setting a psychological bottom price for themselves, as if reaching that price means it's a solid, unbreakable floor?

Isn't buying now better than chasing at 100,000 or buying at the top at 120,000?
Buying a little now, doesn't it mean you still have ammo to enter at key positions later, without missing out on potential opportunities?
Every time there's a dip and some sideways movement, entering the market is a form of bottom fishing in itself. The market is disorderly and chaotic; in the crypto space, there are no fundamentals. Just look at the charts, close your eyes, and go for it, that's all there is to it.
