Bitcoin open interest hits 109-day high at $64.7B amid price rise to $81,550.

Bitcoin's open interest in derivatives surged to $64.7 billion on May 5, the highest in 109 days, reflecting renewed investor interest. This increase follows a recovery from a low of $43.04 billion in early March and coincides with Bitcoin's price rising 2.46% to $81,550. Despite the price gain, many traders are betting on a near-term price reversal, indicated by a drop in the funding rate and a shift toward bearish positions. The recent price surge also triggered profit-taking among spot traders, marking the highest daily realized profit since December 2025.
