Entering late December, Bitcoin's days are not going well. Liquidity has significantly shrunk, volatility has followed suit and decreased, and the previously clear support levels have become blurry—this dull market pattern is likely to be broken by a "big move."

From the weekly performance of implied volatility, it has already approached the support level. At this pace, it probably won't be long before we see a directional trend. The rebound strength on the bullish side has been continuously weakening, which is a sign of a downtrend, and we have to acknowledge that.

Honestly, the price level of 86,700 has been tested too frequently recently. My strategy is very simple: if it hits this level again, I won't move; I will wait patiently until the 85,000-84,000 range. For the orders that were false breakouts at 86,700 yesterday and then recovered, you can set a cost price protection to insure first, then see how long you can hold.
