Online reported that 67-year-old retired artist Ed Suman suffered a fake Coinbase customer service scam earlier this year and lost more than $2 million in cryptocurrency. Suman has been engaged in metal processing in the art world for nearly 20 years and has participated in the production of well-known artworks such as Jeff Koons '"Balloon Dog" sculpture. After retirement, he invested most of his savings in cryptocurrency, holding a total of 17.5 bitcoins and 225 Ethereum, all of which were stored in the Trezor ModelOne hardware wallet. In March this year, Suman received a text message disguised as Coinbase warning him of an abnormal login to his account. Then a fraudster who called himself "Coinbase Security Commissioner Brett Miller" accurately said his hardware wallet information over the phone and induced him to enter mnemonic words on a counterfeit website, citing a "security upgrade." Nine days later, another scammer tried the same trick again and eventually cleared all his encrypted assets.
