BroadChain News, April 22, 15:30, the Coinbase Premium Index has remained positive for 14 consecutive trading days since April 9, marking the longest bullish signal since Bitcoin hit an all-time high of $126,000 in October 2025. This index measures the price difference between Coinbase and global exchanges like Binance, with a positive value indicating more aggressive bidding from US buyers.
Coinbase is the primary trading platform for US institutional investors, and its sustained premium reflects that large funds, including corporate treasuries, hedge funds, and spot ETFs, are actively increasing their Bitcoin holdings. This trend is similar to the market structure before BTC reached its all-time high last October, when the premium index also remained positive for an extended period.
Analysts point out that the continuous influx of institutional buying is a key driver pushing Bitcoin prices higher. If the premium index remains positive, BTC is likely to maintain strong performance in the short term. However, caution is warranted as a decline in the premium could signal weakening buying momentum. Currently, Bitcoin is trading around $120,000, and the market is closely watching subsequent changes in institutional capital flows.
