"Bull tops don't surge high, bear bottoms don't fall deeply," known in finance as volatility convergence. If this is truly the 2019 script, what happened in March 2020? -> Answer: The liquidity crisis caused the "312" crash, which directly broke through all support levels. Conclusion: Structurally, it may resemble 2019 Line 4 -> Line 2, but we must guard against macro black swans like a stock market crash causing Line 2 to be lost. Technical confirmation of price action: Currently, the price is near Line 2. We need to see a volume test without breaking below, or a quick rebound after a spike. Structural cross-validation: $74,000 is the previous major high/breakout point from early 2024 in the last bull market. Previous highs turning into support is a classic technical reason for bullishness. Resonance: On-chain Line 2 + technical support $74k resonance. This is a high-probability trading point, but not a guaranteed win. History rhymes but does not simply repeat.
