According to data from TheBlock, as reported by Jinse Finance, the active supply of Bitcoin and Ethereum in the past year has reached a historic low. Between March 2017 and 2018, more than 59% of Bitcoin's supply was active. However, in the past year, only 30.12% of Bitcoin's supply changed hands. Ethereum saw more than 86% of its supply change hands between July 2016 and 2017, but last year only 39.15% of its supply changed hands, also setting a historic low. For Bitcoin, the historic low in active supply is usually before the block issuance reward is halved, which is expected to happen in 155 days (April 24, 2020).
