Rain Lõhmus, the founder of Estonia-based LHV Bank, has revealed that he is the owner of a massive 250,000 Ether stash. However, he has also revealed that he has lost the private key to the wallet containing his Ether, meaning that he is unable to access it. Lõhmus has said that he is not willing to give up on his Ether and that he is open to paying someone who can help him to recover it. However, he has also said that he is not sure if it is possible to recover the Ether, given that he has lost the private key. The story of Lõhmus' lost Ether is a reminder of the importance of storing cryptocurrency securely. Private keys should always be stored in a safe place and should never be shared with anyone.
