Bitcoin's on-chain activity has surged, with Coin Days Destroyed (CDD) reaching 4.9, indicating significant movement among long-term holders. This spike suggests renewed activity as older coins are being moved in large volumes, reminiscent of past major market shifts. Bitcoin is trading near $144,000, with several on-chain metrics, such as SOPR ratios and LTH realized price, pointing to increased profit-taking and structural support above critical levels.
