ETH: Free Float Market Cap
Shown as its 2019–2022 sample; the latest readings and full history are included with Plus.
The value of the ETH that can realistically change hands: price x free float.
Why use it. Market cap also counts coins that will probably never trade: lost coins, coins unmoved for a decade and the project's own holdings. Free float value is the part of the market cap the market actually prices. How to read it. A widening gap to Market Cap means more of the supply is locked away, dormant or held back; a narrowing gap means it is coming back into reach of the market.
Calculation. Price x free float, where free float is the ETH held on the execution layer less ETH unmoved for 10 years or more; ETH staked on the consensus layer is left out, as it can only leave through the withdrawal queue. Supply from CryptoKeyhole's own Ethereum node (Ethereum's Circulating Supply chart), price from CryptoKeyhole's own USD index of public exchange markets. One value per UTC day, at the day's close; the latest complete day appears once our nodes have published it.
