In its latest chart analysis, Matrixport points out that Bitcoin remains in a correction phase after breaking below a key technical level. It states that the 21-week moving average is a core indicator for observing the shift between bullish and bearish trends in Bitcoin. Historically, this moving average has provided good follow-up signals during uptrends and often warns of risks before sharp pullbacks, helping investors avoid significant downward volatility. Reviewing the current price action, Matrixport notes that when Bitcoin broke below the 21-week moving average in the fourth quarter, it already indicated a potential for further market correction. Although a rebound occurred in late December, the price quickly came under pressure and fell back after approaching the 21-week moving average, failing to regain a foothold above it. Based on this assessment, Bitcoin's overall structure remains in a correction range. Matrixport also points out that a tactical rebound is possible in the short term, but so far, there are no clear signals sufficient to support a new round of sustained upward movement.
