Retired artist Ed Suman was scammed by fake Coinbase customer service, losing more than $2 million in cryptocurrency

Ed Suman, a 67-year-old retired artist, lost more than $2 million in cryptocurrency earlier this year in a fake Coinbase customer service scam. Suman worked in the art world for nearly two decades in metalworking, working on well-known artworks such as Jeff Koons' "Balloon Dog" sculpture. After retiring, he put most of his savings into cryptocurrencies, holding 17.5 bitcoins and 225 ethereum, which are stored in Trezor ModelOne hardware wallets.
In March of this year, Suman received a text message disguised as Coinbase warning of an abnormal login to his account. Then a scammer claiming to be "Coinbase Security Commissioner Brett Miller" accurately stated his hardware wallet information over the phone and induced him to enter mnemonic words on the counterfeit website on the grounds of "security upgrade". Nine days later, another scammer repeated the same trick and eventually emptied his entire crypto assets.
