$1M stone NFT sold for one cent user error

It’s been a tough life for cryptocurrency users. On March 10, an awkward keystroke and the actions of a sniper robot resulted in a $1 million mistake.

A stone worth 444 Ether (ETH) or $1.2 million was sold to a bot for 444 Wei ($0.0012), while the seller, DinoDealer, confused WEI and ETH. In one tweet, the seller said “with one click, my entire ~$1 million net worth was gone.”

How is your week?


I just put it wrong @etherrock #44 by 444 wei instead of 444 eth‍♂️

Bot fires the same block and tries to flip to 234 eth

One click and my entire ~$1 million net worth disappeared

Is there any hope?

“Sniper bot” refers to a sniper bot, first used on the eBay auction site. Buyers who want to time their bids down to the last second use these tools. Now, they are very prolific on the list of non-fungible tokens (NFTs). Popular freelance site Upwork currently lists robotic sniper tools for the NFT OpenSea platform, starting at just $200.

Once a bot captures an NFT or digital receipt, there is no turning back. Blockchains are built to be immutable, so simple mistakes like confusing ETH and WEI can be very expensive.

In fact, human error is common in the cryptocurrency world. An unfortunate Bitcoin (BTC) user recently lost $10,000 (0.25 BTC) in a mistake that could have been avoided had they reverified the recipient’s wallet address.

The seller, DinoDealer, appears to have accepted the loss and publicly shared the address of the stone sniper robot. He played down the situation by uploading a new Twitter profile picture and adding a crying emoji after his Twitter handle. His head is next to the gem, crossed out in red.

More jokes come from DinoDealer’s futile attempt to contact “crypto customer service.” He tried to speak to members of the crypto community, but was responded by suspicious users who wanted to help, providing email addresses and WhatsApp numbers.

Do not contact these numbers or email addresses.

The past month has been filled with seemingly small mistakes with potentially dire consequences. It has become increasingly common for a simple mistake to lose millions of dollars in market value in some cases.

Coinbase white hat hackers discovered a potentially market-destroying bug in the Coinbase Pro code, while frantic bot trading behavior drained the launch of 58 ETH of WTF tokens. The “poor pool liquidity management” exposed the release.

On better days for DinoDealer, other crypto rock enthusiasts came to help him, with one user sending a geologist seller a photo of the rock with glasses and headphones signed “mfer rocks.”
