The Coin Days Destroyed (CDD) is a key metric that measures the movement of coins by weighting transactions based on how long these assets have been held. Thus, such a huge uptick in the metric signals a significant movement of long-held coins.
According to the on-chain platform, the coin days destroyed for Solana year-to-date (YTD) reached approximately 3.55 billion SOL on Tuesday, marking its third-largest spike since the beginning of this year.
