ChainCatcher Message, CryptoQuant Analyst Maartunn pointed out on platform X that the sixty-day moving average of Coin Days Destroyed (CDD) has reached a new high in six years. CDD is an important on-chain data analysis metric used to measure market activity for Bitcoin. Specifically, CDD calculates the product of the 'dormant days' held by Bitcoin when it is spent and the 'transfer amount.' The rise of this metric may indicate that more long-term held Bitcoin is being transferred or sold in the market, which is worth investors' close attention regarding its potential impact on market prices and market capitalization rankings.
