About this comparison

Divide Ethereum's stored market cap by the selected Bitcoin supply to find the implied BTC price. The starting assumption is circulating supply of the base asset; the reference asset's supply is not substituted. Quotes use the same currency, with each source timestamp shown above. This is a valuation comparison, not a prediction or a measure of money inflow.
