How Is the Fair Market Value of Crypto Determined for a Purchase Transaction?

The fair market value (FMV) of the crypto used in a purchase transaction is determined by the value of the crypto in US dollars (or local fiat currency) at the exact date and time the transaction occurred. This value is typically sourced from a reputable cryptocurrency exchange or an aggregated price index.

This FMV is used both as the sale price for the capital gains calculation and the cost of the purchased good or service.
