Brief Description: Normalized Coin Days Destroyed (CDD) by spending, relative to total Bitcoin supply.
aCoinDaysDestroyed_LTH measures the aggregate CDD from UTXOs spent in the last day, normalized by the total Bitcoin supply.
Interpretation aCoinDaysDestroyed_LTH is a lens through which one can gauge market behavior in Bitcoin. A high value indicates that a significant amount of bitcoins that were dormant for extended periods has been transferred, potentially signalling changes in market sentiment. This could suggest that long-term holders are taking profits or reallocating assets.
Conversely, low values of aCoinDaysDestroyed_LTH imply that the market is largely driven by newer coins, which may suggest a trend of accumulation.
Advanced Explanation To understand aCoinDaysDestroyed_LTH more technically, consider that each bitcoin generates one 'coinday' each day it remains unspent in a wallet. If a user holds 10 bitcoins for 10 days and then spends them, 100 'coindays' are destroyed.
aCoinDaysDestroyed_LTH = ∑(Spent_UTXO_BTC_value * Spent_UTXO_Age) / Total_Supply
where
- Spent_UTXO_BTC_value is the bitcoin value of each spent UTXO
- Spent_UTXO_Age is the age (in days) of each spent UTXO.
- Total_Supply is the total supply of all bitcoins
