BTC Market Cap: $1.65T

What every bitcoin in existence is worth, added together. It is simply today's price multiplied by the number of coins mined so far, which is why this line looks almost identical to the price chart. One value per calendar day.

The dollar value obtained by multiplying one bitcoin’s price by the total supply recorded for the same date. It compares Bitcoin’s market size with other assets; it is not money invested.

The coin count barely changes from one day to the next, so this line rises and falls with the price and tells you almost the same story. Use it for a sense of scale rather than for timing.

For example, at about $2.2 trillion, all bitcoin together is worth roughly a tenth of all the gold in the world and about the same as one very large technology company.

Market cap = stored BTC price in USD × stored total supply on the same UTC date. Price uses blockchain.info or the previous completed Coinbase BTC-USD daily close. Supply uses blockchain.info or our Bitcoin Core node’s scheduled issuance. Both input sources are recorded.

We calculate this series; it is not a direct provider market-cap feed. A date needs both inputs. Supply includes genesis and lost coins and is not spendable UTXO value. A fresh price alone cannot make market cap current.

Calculated: stored BTC price × total supply for the same date
