最新报道:Coinbase's Bitcoin premium has turned negative for the first time since October 2023, signaling weaker U.S. investor demand. The premium, which reflects the price difference between Coinbase and Binance, dropped to -$50 this week as Bitcoin traded around $42,000. Analysts note this shift suggests reduced institutional buying pressure, potentially linked to outflows from the Grayscale Bitcoin Trust (GBTC). Meanwhile, Bitcoin's open interest in futures markets has declined by 20% since January 12, indicating cooling speculative activity amid the recent price correction.
