think of this. if yesterday btc is 2600.
today becomes 1800. all the big buyers jumped in and buy it.
what happened to seller ?
seller got burned badly. so seller don't dare to sell way too low.
and btc market capitalisation is the biggest of all, which makes it the most expensive one to short in a bull market.
all the drop is massive dumping by whales (probably exchange cartels) to kick those margin traders.
I just put an analogy. if wootz were to liquidate, he would not dump 20k ETH in one blow because it would simply collapse let's say $70.
genuine sellers always want to sell high. not sell low.
so they would sell bit by bit over some period to get better price, sell more on the top area.
but I've seen far too many times when btc crashes u see waves of 100-200btc being dumped onto buyers in flashes of seconds.
buyers cratered layer by layers until eventually sellers got too close to massive buy wall.
buy wall could also be the sellers themselves.
by whacking anything in between to faint and die like margin traders, they pick up their position at a much lower price.
then sellers squared off, closing their short positions and things get "normal" again.
usually this punching, hammering has its own range, around 30-35% for BTC is a very much safe range to get in as seller themselves already exhausted
this range has been maximum pullback range for a couple of years now.
but other coins range is different. ETH 40%. ANS 50%. others might be more.
btc is volatile but because it's established position as money and practical usage it won't crash 50% as long as all the exchanges are intact and serving all continents.
dunt take my word for it. do ur own homework n calculate fluctuation for those established, with practical usage coins, with large market capital.
2year maximum swing range. should be more volatile as this price is average price, so it does not compute the volatile maximum range.

I see I see. I'm no good in all these. Guess have to learn.
That's the reason I'm more of a HODLer. If day/margin trade, sure die.
