ChainCatcher message, Coinglass data shows that Coinbase's Bitcoin premium index turned positive again after 22 days, but this positive status lasted only one day and has now turned "negative" again, currently at -0.0277%. The Coinbase Bitcoin premium index measures the difference between the Bitcoin price on Coinbase (a major U.S. trading platform) and the global market average price. A negative premium typically reflects stronger selling pressure in the U.S. market, declining investor risk appetite, rising market risk-averse sentiment, or capital outflows.
