This non-fungible token (NFT) collector lost a million dollars due to a blunder.
NFT collection, EtherRock was listed at 444 wei instead of 444 ether, according to Twitter user Dino Dealer. Wei is the smallest denomination, hence it’s a scary story. In actuality, one ether equals 1,000,000,000,000,000,000 wei, according to Entrepreneur. As a result, the lucrative million-dollar NFT was sold for pennies on the dollar.
For those unfamiliar with EtherRock, it debuted in 2017 following CryptoPunks, and just 100 are now available, according to the company’s website. The value of the rock will rise with each subsequent addition. According to Vice, a $3.5 million bid was submitted for one EtherRock in October of last year. Dino Dealer had hoped to secure his big triumph, but he was met with disappointment instead.
How was your week? Mine? I just mistakenly listed @etherrock #44 for 444 wei instead of 444 eth,” user Dino Dealer wrote on Twitter. “A bot acquired it on the same block and tried to flip for 234 eth. (SIC) In one click, my entire net worth of ~1 million dollars was gone. Is there any hope? Am I GMI? Can snipers show mercy?”
Dino Dealer wrote a series of messages after recognizing his error, asking for a refund on Etherscan.

“Hello ser. Can you return the other rock? I made a huge mistake. Your bot snapped it up in the same block as my transaction so I never had a chance. I hope you can find it in your heart to show mercy, please?” Dino Dealer wrote in the comment section.
As of now, it does not appear that mercy was shown, as the user has the NFT listed for 234 ETH (USD 600,000), according to Vice.
