最新报道:Cryptocurrency markets rebounded sharply on Tuesday, with Bitcoin surpassing $91,000 and Ether reclaiming $3,000, as traders reacted to heightened Federal Reserve rate-cut expectations and a surge in U.S. ETF activity. The rally coincided with Vanguard lifting its ban on Bitcoin ETF purchases and Bank of America allowing its advisors to allocate 1%-4% of client portfolios to crypto. Analysts linked the intraday surge to renewed institutional access, while a potential SEC "innovation exemption" for crypto rulemaking added to the positive sentiment.
