Still down, but currently around the 91,500 support level.

Be a little more patient, don't rush, and confirm the 4H trend line.
Once a bottom is formed, go in; if there's no bottoming indicator, wait patiently, especially watch the US stock market opening in the evening.
Currently, it's a second test; if support doesn't hold, it could drop to around 90,000.
Once near 90,000, I think the opportunity is quite good. If the US stocks stabilize, the chance of BTC returning to 88,000 is not high.
Conversely, if it drops back to around 88,000, then take it easy.
There will definitely be big moves in the first half of this year, whether early or late; a drop doesn't mean there's no market, it could also be a shakeout before the next move.
