Coin age in cryptocurrency refers to the product of the number of coins held multiplied by the duration they have been held without being spent. It is used in some Proof of Stake consensus mechanisms to determine block validation priority, with older coins having a higher chance of being selected. On-chain analysts also track coin age metrics to distinguish between long-term holder activity and short-term speculative movements on the network.
Example
“The protocol favored validators with higher coin age, encouraging participants to hold their tokens longer to earn staking rewards.”
