Bitcoin's 1+ year HODL line is showing a decline from peak levels, a pattern historically linked to previous cycle tops, according to Coinomedia. This metric, which tracks the percentage of Bitcoin supply held by wallets inactive for over a year, indicates increased selling pressure from long-term holders. Such behavior has historically preceded market downturns, as seen in 2013, 2017, and 2021. The current decline in the HODL line suggests that the bullish trend may be nearing its end in late 2025. Long-term holders, often considered 'smart money,' are reducing their positions, which could signal a potential market shift. This trend highlights the importance of monitoring long-term holder activity as a market indicator.
