Ethereum News Today: Estonian Banker Loses $1 Billion in Ethereum Due to Lost Private Key

A former founder of Estonia’s LHV Bank, Rain Lõhmus, invested $75,000 in Ethereum’s 2015 initial coin offering (ICO) and acquired 250,000 ETH at a cost of $0.30 per token [1]. At the time, the investment was modest and unremarkable, but as Ethereum’s value surged over the years, the 250,000 ETH in Lõhmus’s wallet grew to exceed $1 billion [2].

Lõhmus has since lost access to the wallet [3]. The cause is straightforward: the private key associated with the account is missing, and without it, the funds are effectively frozen. Lõhmus confirmed the loss and indicated that he had not pursued any significant recovery efforts. While he briefly considered using artificial intelligence to reconstruct the key, no viable solution has emerged. The design of Ethereum’s blockchain offers no reset function or administrator access—once a private key is lost, the funds are irretrievable.

The case has drawn comparisons to other high-profile lost cryptocurrency fortunes. For example, Stefan Thomas, former CTO of Ripple, lost access to a USB drive containing 7,002 BTC. Similarly, an early Bitcoin investor who owned 6,000 BTC had his wallet keys discarded by a cleaner after his arrest, rendering the assets inaccessible [1]. These cases highlight a growing concern in the crypto community: the irreversible nature of lost private keys and the lack of centralized mechanisms for account recovery.

Lõhmus’s experience underscores the operational risks of holding large crypto assets without robust key management strategies. While cold storage is widely regarded as one of the safest methods for protecting digital assets, it requires disciplined and secure backup procedures. Analysts note that a meaningful share of ETH may already be effectively lost due to forgotten or misplaced keys [2]. Investors are increasingly advised to implement multi-signature wallets, hardware wallet backups, and institutional custodial services for large holdings.

The situation also raises broader questions about the long-term viability of self-custody models. In traditional finance, lost access can typically be resolved through identity verification and customer support. In the crypto space, however, security is non-negotiable—once a key is lost, so is the asset. Lõhmus’s case serves as a cautionary tale for investors who may not fully appreciate the technical and logistical challenges of secure digital asset management.
