Conor Grogan, director of product strategy and business operations at Coinbase, tweeted that due to various errors (user errors, contract defects, etc.), the market has lost more than 636,000 ETH (about 1.15 billion U.S. dollars) forever, accounting for 0.5% of the circulating supply. . About half of this (about 306,000 ETH) was due to a bug in the Parity crypto wallet in 2017, in addition to crypto exchange Quadriga losing 60,000 ETH due to a contract glitch, and the Akutars NFT series losing 11,500 ETH in the failed Mint ETH, and Ethereum users have sent a total of 24,000 ETH to the destruction address.
