Crypto markets ended Aug. 29 virtually flat near $2.73 trillion after fluctuating between below $2.7 trillion and $2.79 trillion, following a rally that added more than $500 billion the previous week. Bitcoin rebounded from approximately $63,500 toward $80,000 and briefly above $81,000, reaching a weekly high near $81,455, before Federal Reserve Chair Kevin Warsh’s inaugural Jackson Hole address pushed it below $77,000; it later recovered toward $78,000 to finish the week up 1% and remained on track for August gains exceeding 20%. QCP Capital said roughly $2.8 billion entered U.S. spot bitcoin ETFs across eight consecutive sessions, while falling futures open interest, contained funding rates and short covering indicated spot demand was driving the rally, although ETFs recorded $202 million in Friday outflows. Warsh’s remarks raised estimated September rate-hike odds from about 35% to 56%-60%, while broader crypto liquidations reached approximately $300 million. Altcoins diverged sharply, even as total altcoin capitalization rose more than 4%.
