Overnight, the market sentiment has completely changed. Last week, anxious investors were still dominated by fear, but today they are starting to take steps forward. Christmas hasn't arrived yet, but the "Santa Claus" has appeared early — this week, the crypto market has experienced a rare overall warming, with Bitcoin successfully breaking through $89,000, and Ethereum regaining the $3,000 level. Even gold has taken the opportunity to hit new highs, while crude oil remains stuck in a mid-range tug-of-war.

Having been in this circle for seven or eight years, I am most sensitive to changes in market temperature. Under this emotional reversal, is it a genuine trend reversal or just a technical short-term rebound? We need to look at three key signals.

**First hurdle: Technical breakthrough**

The significance of Bitcoin reclaiming $89,000 is deeper than you think. This is not only a psychological milestone but also a technical resistance level that has been repeatedly contested recently. Looking at the daily chart, Bitcoin needs to stabilize here to prove the validity of the breakout.

What’s the good news? Moving averages are giving positive signals — 8 out of 10 major moving averages are flashing buy signals. The RSI indicator is at 56.459, in a neutral to slightly bullish zone; MACD also confirms a buy signal. These technical tools together suggest that the upward momentum is quite solid.

In the short term, the $88,421 level is particularly critical, as it determines Bitcoin’s next direction. The price successfully broke through this level yesterday, and today’s performance will be very important.
