**Friday Market Turnaround: After a Surge and Pullback, a Wait-and-See Period, BTC Faces Second Test at the 90,000 Level**

The recent three-day trend is very clear—BTC has been gradually declining since the high of 94,415 on the evening of January 6. The current price of 91,220 has already fallen about 3.5% from the high. This correction is normal and belongs to profit-taking by funds that chased the high earlier; the bullish structure itself has not been broken.

**Where is the Key Support Level**

The price is approaching the extremely critical support zone of 90,000-91,000. Previously, 90,000 was an absolute ceiling; now, it remains to be seen whether it can truly turn into a trading bottom. From another perspective, the depth of buy orders above this integer level directly determines whether the subsequent market can continue upward.

**Friday’s Rhythm Might Be Like This**

Today’s Asian session is relatively weak. If there is no effective rebound in the European session this afternoon, major funds in the US stock market tonight are likely to "pin down" downward, probing the defense strength of the 90,000 integer level.

**Layered View of Key Support Levels**

In the short term (today through the weekend), the most important support to watch is 90,800. This is the lower boundary of the past 12 hours of fluctuation and the last line of defense for the short-term bulls. Breaking below this level would directly test 90,000. The true bottom is between 90,000 and 90,200; as long as this line holds, the main upward trend of this bull market remains unchanged. Below that, 89,500 acts as a trap support to prevent major players from breaking stops and triggering false signals.
