# Coin Days Destroyed

`GET /btc/network-indicator/cdd`

Coin Days Destroyed reflects market participants who have been in the bitcoin on-chain for longer. This indicator gives more weight to long-term-holder position.
`cdd` is the sum of products of spent transaction output alive days and its value.
`sa_cdd` is abbreviation of supply-adjusted cdd.
Since `cdd` increases as the newly created block mined, we need an indicator which normalize `cdd` value. `sa_cdd` is calculated by `cdd` over `supply_total`.
`average_sa_cdd` is the average value of `sa_cdd` since genesis block.
`binary_cdd` is the signal whether current `sa_cdd` is larger than `average_sa_cdd` or not. If `sa_cdd` > `average_sa_cdd`, then `binary_cdd` is 1.
In conclusion, these indicators help us to estimate how whale's moving.
