"BTC large pie 7-day and 30-day lines are about to converge; if it cannot hold in the short term, it will test the 60-day line" is a technical analysis viewpoint based on moving averages. Here is a detailed explanation for you:

Meaning of moving averages

- 7-day moving average: Reflects the average closing price of Bitcoin over the past 7 days, quickly capturing short-term price volatility trends. When the price is above the 7-day moving average, it indicates a bullish market; conversely, it indicates a bearish market.

- 30-day moving average: Compared to the 7-day moving average, the 30-day moving average considers a longer time span, filtering out some short-term market noise and more smoothly reflecting the medium-term price trend.

- 60-day moving average: Usually regarded as an important medium-term support or resistance level. If the price falls below the 60-day moving average, it may indicate a change in the medium-term trend, and market sentiment may shift from bullish to bearish.

Significance of the convergence of the 7-day and 30-day moving averages

- Signals of trend reversal: When the 7-day moving average converges with the 30-day moving average, this is usually seen as an important signal indicating that short-term and medium-term trends may be reversing. If the price was in an upward trend before this, the convergence may suggest a weakening of the upward momentum, and the market may enter a correction period; conversely, if the price was in a downward trend, the convergence may indicate a slowdown in the downward trend, and a rebound may even occur.

- Uncertainty in market direction: The convergence of moving averages also indicates that the market is in a relatively balanced state, with the forces of bulls and bears temporarily in equilibrium. In this situation, the market direction is more difficult to predict, and close attention should be paid to subsequent price movements and changes in trading volume.

Testing short-term support and the 60-day line

- Importance of short-term support: If the price cannot hold this support level after the convergence of the 7-day and 30-day moving averages, the market may further decline to test the support of the 60-day moving average. The 60-day moving average, as an important medium-term support level, will have a significant impact on the medium-term trend of the market depending on the strength of its support.

- Test results of the 60-day line: If the price finds support and rebounds near the 60-day moving average, it may mean that the market has only experienced a short-term adjustment, and the medium-term trend remains upward; however, if the price falls below the 60-day moving average, the market may enter a longer adjustment period, potentially triggering greater selling pressure.

Other factors to pay attention to

- Trading volume: Changes in trading volume are crucial for assessing the strength of market trends. If there is a significant increase in trading volume during the convergence of moving averages or when testing the 60-day moving average, it may indicate that market participants' emotions are more intense, and the trend reversal is more certain; conversely, if trading volume is low, the market may just be undergoing a short-term adjustment, and the trend reversal may not be so obvious.

- Market sentiment and news: In addition to technical analysis, market sentiment and news can also have a significant impact on prices. For example, if there is significant positive or negative news in the market, prices may break through the expectations of technical analysis and experience significant fluctuations.
