Bitcoin’s supply will cap at 21 million BTC, with analysts estimating the final Bitcoin will be mined in the year 2140. At the time of writing, roughly 18.8 million BTC are in circulation. However access to one fifth of all Bitcoin (or more) is believed to have been lost, meaning that asset managers and companies may control an even greater share of the supply.

While large entities are gobbling up BTC, Ethereum has appeared to have been undergoing a supply shock of its own in the wake of its London upgrades that introduced a burn mechanism to the crypto asset’s fee market.

According to Watch The Burn, 97,369 Ether worth $313.5 million has been destroyed in the 21 days since London, meaning that roughly 4,637 ETH are being burned daily on average. Overall, Ethereum’s burn mechanism has resulted in 35% a net reduction in the number of newly minted Ether entering supply.
