Bitcoin is approaching a supply-heavy zone between $80,000 and $82,500, where the on-chain cost basis of a large amount of BTC is concentrated from the final rally before the sell-off. As of Aug. 26, U.S. spot ETFs had recorded inflows for eight consecutive trading days, totaling about $2.8 billion, while August inflows reached approximately $3.3 billion, the highest monthly figure this year. On-chain data showed a positive seven-day moving average for net realized profit and loss, at about $752 million, with realized profits near $1.1 billion and realized losses of $354 million. Garrett Jin said continued closes above $82,500 would suggest that coin turnover is nearing completion and the available supply has been sufficiently absorbed. The key downside level is $76,600, near the cost basis of short-term holders. A one-day close below that level would remain manageable, but simultaneous deterioration in at least two of ETF flows, the Coinbase premium and the seven-day exponential moving average of net realized profit and loss would constitute a warning. An address associated with Garrett Jin added 600 BTC to a long position at $79,000 early on Aug. 26, worth $47.4 million.
