btc has rebounded from 80600 to 93000 for about 10 days, then suddenly plummeted the day before yesterday, and yesterday it pulled back again. This is actually easy to understand; it's just that the market maker is capturing liquidity. After such a long rebound, many thought it had stabilized and started to go long, but a sharp drop took out those chasing the long positions. Moreover, the sudden drop creates the illusion for some shorts that there will be another drop, prompting them to short again. As a result, the market maker quickly pulled it back, completing the liquidity capture.
