Velocity is a measurement of the rate at which an asset is exchanged. It can be thought of as a rate of turnover, or, in other words, the number of times that an average unit of an asset has been transferred within the last year. In the above chart, we calculate velocity by dividing BTC’s adjusted transfer value over the past year (which is the total amount of cryptoasset transferred) by BTC’s total supply. Historically BTC’s velocity has increased during a rising bull cycle as on-chain activity increases, and has dipped following both the 2013 and 2017 price peaks. If velocity starts to slow dramatically, it could be read as a sign that the bull phase is reaching its end.
