BTC: After breaking past $81,000, it was pulled back on Friday by macro factors. Just one day after BTC regained the $81,000 level, it was pressured again by U.S. employment data. BTC is currently trading around $80,000. Several data points should be considered together to understand this volatility: First, on September 3, U.S. spot BTC ETFs saw net inflows of approximately $731 million—the largest single-day inflow this year. Second, BTC futures open interest has recently risen back to around $55 billion, indicating a clear return of leverage. Third, the $81,000 level is a well-defined near-term price resistance zone. The current structure is not complicated: ETF inflows represent genuine demand; Rising open interest reflects increased derivatives participation; But sudden shifts in macro interest rate expectations can still suppress risk assets. The $80,000 level now functions more like a confirmation zone for bulls and bears. If BTC can reclaim $81,000 while ETF inflows continue and open interest does not surge uncontrollably, any breakout would likely be of higher quality. Conversely, if price falls back below $79,000 while open interest remains elevated, there is a risk of further leveraged liquidations. At this stage, it’s premature to define a single breakout as the start of a new trend. First, observe how price behaves within the $79,000–$81,000 range.
