币界网报道:Cryptocurrency markets surged today driven by strong inflows into Bitcoin ETFs and renewed speculative interest. Major ETFs like BlackRock's IBIT and Fidelity's FBTC saw significant capital inflows, boosting Bitcoin's price above $67,000. Analysts attribute the rally to growing institutional participation and positive sentiment around potential Ethereum ETF approvals. Meanwhile, altcoins also gained momentum as traders rotated profits from Bitcoin into smaller-cap tokens. The crypto fear and greed index entered "extreme greed" territory, signaling heightened market optimism. However, some experts caution about potential volatility ahead as macroeconomic uncertainties persist.
