CoinWorld News: According to CoinWorld data, the Coinbase Bitcoin Premium Index has been in a negative premium range for 47 consecutive days (since May 19), with the latest value at -0.1007%. This index measures the deviation of BTC prices on Coinbase (a mainstream compliant platform in the US) from the global average, and sustained negative values indicate heavy selling pressure on the US market, decreased risk appetite, capital outflows, or increased risk aversion. Historical data shows that prolonged negative premiums are often accompanied by the withdrawal of US institutional funds, warranting caution regarding short-term pullback pressure. Previously, the index was in negative premium for 40 consecutive days from January 16 to February 24 this year, setting the longest consecutive negative premium record since the index was introduced, surpassing the approximately 30 consecutive days of negative premium during the "1011 crash" period.
