This morning at 7 o'clock, BTC suddenly took a hard hit—from around $90,000 it was directly smashed down to $85,600. With this long Bearish line, many people probably got liquidated in their sleep.

But to be honest, although this drop is sudden, it is not unexpected. A closer look at the market will reveal that this is more like a release of emotions that have been building up for several days, rather than a "black swan" type of crash.

**Let's talk about why the rise has lost momentum**

Looking back at the price movements from a week ago, the rebound from November 27th to 29th has already shown signs of fatigue: each time the K-line rises, the body gets smaller, and the highs are getting lower. There have been multiple attempts to break above 91,500, but none have succeeded, and it is clear that the funds do not want to continue pushing higher. This state of "wanting to rise but unable to" is actually building up energy for a decline.

The bulls have not completely retreated yet, but their enthusiasm has clearly cooled. Today's drop essentially releases the accumulated weakness from the past few days all at once.

**Signals revealed by moving average crossover**

There is a very obvious change technically: MA7 started to flatten out yesterday, and this morning it directly crossed below MA30 significantly, accompanied by this large Bearish line.

The crossover of the short-term moving average over the long-term moving average usually indicates that the short-term rhythm has been disrupted. It is not just the profit-taking that is being sold off, but also the presence of short-selling forces—sellers have temporarily gained the upper hand.

This wave of decline is not a simple pullback, but a structural change at the emotional level.

**What happens after the sharp drop?**

It is worth noting that after the drop, there was no further breakdown and loss of control, but rather a quick formation of signs of stabilization at the low level.
