Definition

Recall that the coin-age model allows us at each given point in time to assign age to each coin/token.

There are two coin age defined metrics:

  • Mean Coin Age - The average age of all coins/tokens on the blockchain.
  • Mean Dollar Invested Age - The average age of all coins/tokens on the blockchain weighted by the purchase price.

Example (Mean Coin age)

Given there are 100 tokens in existence:

  • 50 of them have age 10 days
  • 50 of them have age 20 days

then the average coin age is: (10 × 50 + 20 × 50) / 100 = 15 (coin-days)

Example (Mean Dollar Invested Age)

Given there 100 tokens in existence:

  • 50 of them have age 10 days and the token's price was $1 at that time
  • 50 of them have age 20 days and the token's price was $2 at that time

then the mean dollar invested age is: (10 × 50 + 20 × 50) / (50 × $1 + 50 × $2) = 1500 / 150 = 10 (coin-dollar days)
