Based on the current chart structure, BTC has gained effective liquidity support after reaching 74500 and successfully broke through the downward pressure line extending from the 82000 high point. The current market is in the structural backtesting stage after the breakthrough. The current price has just fallen back to the intersection of the "original downward resistance line" and the "recently rising bottom support line", which is a resonance test point on the technical level. In objective right-hand trading logic, the first retracement after a breakthrough usually provides a high profit or loss entry window, as the defensive boundaries are very clear. Supporting observation area: 76500-77000 This range is the defensive core where the dual trend lines intersect, and as long as the price stabilizes above this level, the bullish reversal logic still holds. Upward resistance zone: 80000-82000 If the backtesting is effective, the initial upward resistance is at the 80000 integer level, and further key structural suppression is high before 82000. Risk control (stop loss): If the K-line entity effectively falls below 76000 and closes within the downtrend line, it indicates that this breakthrough is a false breakthrough, and the original bullish logic has been falsified, requiring strict stop loss and exit. The current position does not require predicting that the market will definitely rise, but based on the objective conditions of "reasonable profit and loss ratio and clear stop loss" to place bets, respect the market structure, manage risks well, and follow discipline.
