Long-term Bitcoin holders are gradually selling their holdings, according to a recent analysis by Glassnode. The report highlights a lack of strong upward catalysts and an increased risk of short-term pullbacks as reasons for this trend. Glassnode's on-chain model identifies key support levels, with the 0.95 SSD percentile at approximately $103,700 and the 0.85 SSD percentile at $95,600. These levels are crucial to monitor if profit-taking continues.
