Crypto’s Indiana Jones? Coinbase exec helps recover $322K worth of once-lost crypto

cointelegraph.com:

It’s not every day that one discovers they've suddenly become $322,000 richer — but for one lucky crypto investor, this is exactly what happened in the waning hours of July 5.

In a recent Twitter thread, Conor Grogan, the head of product at Coinbase explained how he uncovered hundreds of thousands worth of dormant crypto and even managed to contact its unaware owner.

When the Ethereum blockchain forked in 2016, Ethereum Classic (ETC) was created. Any investor who held the now-standard Ether (ETH) on-chain was airdropped an identical amount of ETC. Many never touched these new funds, said Grogan.

“Forgetting you have funds on chain (or not keeping track of airdrops) is common,” Grogan said, sharing how he’d recovered six-figure amounts for investors in the past. In a subsequent screenshot, Grogan said he once notified a Twitter user of 23 ETH that had been sitting untouched.

Tracking down these wallets is no small task. To start, Grogan said he trawled through the “ETC rich list” searching for accounts that had never touched their ETC. After tracking down roughly 20 addresses that held more than $250,000 worth of ETC he combed through each, looking for ways to get in touch.

Grogan said he ran into a number of “dead ends” with most of the wallets, but at last stumbled upon an address with the prefix "0x475." Interestingly, the wallet contained a cryptocurrency called “EOSDAC,” which was airdropped to Ethereum holders in 2018.

Leveraging the new information, Grogan said the airdrop amount and snapshot date allowed him to connect with the holder’s EOS wallet.

"As it turns out, this EOS wallet has quite the history!" Grogan
