Bitcoin whales who have held the cryptocurrency for over seven years have significantly increased their sell-off activities, according to Charles Edwards, co-founder of Capriole Investments. Edwards shared a chart on the X platform highlighting the on-chain selling activity of these long-term holders, known as Bitcoin OGs. The chart indicates that the sell-off began in November 2024 and has intensified in 2025, with transactions exceeding $500 million marked in red. This trend suggests a notable shift in the behavior of Bitcoin OGs, who are now cashing out in large quantities. The data underscores a significant movement in the market, as these seasoned investors liquidate substantial holdings, potentially impacting Bitcoin's price dynamics.
