Millions of dollars in ETH lie unclaimed in presale wallets — but there's a way to get them back

Out in the cryptosphere, there's a vast amount of wealth that's seemingly out of reach.

A long-running statistic suggests four million Bitcoin — almost 20% of the total supply — has been lost forever. Much of it was mined when the network was just beginning, with early adopters tearing their hair out after losing their private keys. One Welshman has endured a nine-year battle as he attempts to receive a hard drive containing 7,500 BTC from landfill. 

But this isn't the only treasure trove that's worth exploring. For example, did you know that over 500 Ethereum presale wallets are yet to be recovered… and collectively, they have a value of several billion dollars?

Fast forward to now, and the exchange rate is much less generous: 1 BTC will only fetch 12 ETH. A whopping 8,893 people participated in this presale and were given tokens in the genesis block — but according to experts, hundreds of wallets remain untouched.

Some of these wallets contain tens of ETH — a figure that's worth tens of thousands of dollars today. Others have more than 10,000 ETH inside, meaning their owners are missing out on a life-changing $20 million.

Will the upcoming merge — where Ethereum moves from a Proof-of-Work to a Proof-of-Stake blockchain — mean these funds are just irretrievable? And what's more, who in their right mind would lose access to their crypto after taking part in a presale?

Well, there are a plethora of factors that can lead to the private keys of presale wallets being lost. It could have been a
