BTC just completed a 'chip shift upward' yesterday, and today it's already facing its first stress test. After BTC climbed near $65,600, it failed to hold its ground. The footprint chart showed consecutive negative Delta, with aggressive sell orders dominating the market. Especially the last two: -54.02 Delta, -117.50 Delta. The negative Delta expanded significantly, and the price subsequently broke below $64,000. This isn’t just a simple case of 'insufficient buying.' To be more precise, it’s that aggressive sell orders kept hitting the order book, gradually depleting the support formed by the high-level turnover from before. Although there were brief moments of positive Delta during this period, they didn’t push the price into a sustained rebound. This indicates that the buying side’s counterattack was weak, more about localized support rather than regaining control. So right now, the key for BTC isn’t whether it breaks below $64,000, but whether it can hold the chip peak at $63,940 that was broken through yesterday. This is the dividing line: - If the price quickly recovers $63,940 and positive Delta expands, it means yesterday’s chip shift upward is still valid, and the pullback is more like a stress test; - If $63,940 is lost and negative Delta continues to expand, then yesterday’s high-level turnover zone will turn into a short-term trapped area, and we’ll need to look at the past month’s chip POC at $62,602. Below that, there’s support at $62,040 and $61,270. In short: yesterday was about the chip shift upward, today is about whether the support can withstand the aggressive sell orders. A truly healthy breakout isn’t afraid of pullbacks; what it fears is that during the pullback, selling pressure keeps increasing while buying pressure fails to recover.
