After BTC continued to rise from the 62,500 area to a high of 79,500, it entered a stage of high volatility and momentum in the short term. The overall trend structure is bullish, but the upward kinetic energy has slowed down at the margin, and the current price has repeatedly tested around the 77000-78400 range. The key support is located at the 76500 line. If it falls below effectively, it will open up room for a retracement to 75000; the upper pressure will focus on the 78800-79500 area. Only a breakthrough can restart the trend upward attack. The main risks are profit-taking that may occur after high volume and stagflation, as well as short-term selling pressure caused by the loss of the lower edge of the shock range.
