The basis for chart analysis is that history will repeat itself

The technical analysis of charts presupposes a belief in the logic of historical recurrence. So we always look for the future in the historical charts. So for waterfall diving, I've written before about how to deal with the l-shape of bitcoin. Here are two historical references. One is the big dive at the end of 2018, which is almost exactly the same scenario. The other, last October, was also a big waterfall. Both times there was a double dip. So I think the logic is the same, the market will eventually calm down in a panic, and that's the market to talk about new trends.

A big drop can lead to a super rally, but not necessarily a bottom. The first low in the market is usually a low in sentiment rather than a low in value. Then you need to confirm. And this confirmation process is relatively complex, and there are a lot of deformation. So most people get lost in the process. And we do not have an effective way to deal with it. At present, I think the best way is to stay on the sidelines and wait for the second confirmation.

As for v-shaped inversion, I wouldn't rule it out, but for things with small probabilities, it's not a technical category, so I won't discuss it.
