Over 4.65 million dormant Bitcoin (BTC) have been activated in 2025, creating a market impact valued at approximately $500 billion. This significant movement involves nearly half of all BTC that had been inactive for more than five years, leading to notable shifts in trading volume and investor behavior. Analysts indicate that long-term holders are reacting to key price milestones and making portfolio adjustments, which has contributed to increased market pressure and a shift in sentiment. The activation of these dormant assets underscores the dynamic nature of the cryptocurrency market and its susceptibility to changes in holder strategies.
