Coin Age
fundamentals · analytics
The time since a UTXO was created; used in analysis, privacy, and some staking systems.
Coin age measures how long a specific UTXO has remained unspent. Some systems historically used coin age in validation or rewards; analysts use it to study holder behavior and supply dynamics.
- Spending very old coins can deanonymize or draw attention
- Wallets may prefer younger coins for common payments to preserve privacy
