$BTC Bitcoin: $66,500 Faces Resistance, Summer Low-Volatility Pattern Persists

Since July, Bitcoin has continued a typical summer slowdown rhythm. On Tuesday, BTC rose to $66,500, with a gain of about 5% for the week, and 24-hour trading volume of about $33 billion. K33 analysts noted that July is historically the weakest month for BTC trading volume relative to the annual average, with current 30-day trading volume at only 62.4% of the annual average.

ETF fund flows have shown a positive shift. In May, 70% of Bitcoin ETF trading days closed with net outflows; in June, this rose to 90%, while in July so far only 33% of trading days recorded net outflows. U.S. spot Bitcoin ETFs recorded about $203 million in net inflows on Tuesday, marking the sixth straight trading day in positive territory, bringing cumulative inflows to nearly $51.8B.

However, CME open interest has remained below 100k BTC throughout July, falling to the lowest level since October 2023. The market is waiting for the July 28–29 FOMC meeting to provide direction. Bitcoin has gained triple support above $66,000—semiconductor rebound, continued ETF inflows, and falling oil prices—but analysts warned that any reversal could break the current balance#特斯拉持有11509枚BTC近四年未动
