Bitcoin is entering a week defined by four market tests: resistance between $81,000 and $86,000, rising expectations for a 0.25% Federal Reserve rate increase in September, US employment data and oil-price volatility linked to US-Iran tensions. Glassnode says long-term holders have a cost basis for 1.05 million BTC in the $83,000-$86,000 zone, while BTC recently traded near $79,000 and briefly fell below its 50-week exponential moving average at $77,269. CME Group’s FedWatch Tool showed rate-hike odds approaching 60%, up from 41.4% a week earlier. CryptoQuant reported that wallets holding at least 100 BTC added about 60,000 BTC from Aug. 1 through Aug. 30, while wallets holding 1-100 BTC and less than 1 BTC sold about 33,000 BTC and 14,000 BTC, respectively.
