The evolving landscape of cryptocurrency presents significant challenges, especially regarding the estimated amount of Bitcoin that has been lost over the years. While Bitcoin commonly garners attention for its scarcity—limited to 21 million coins—the same can be said for the Ethereum blockchain, albeit with a more flexible supply. The enigma of lost Ethereum coins is gaining traction but has not yet received its fair share of spotlight, yet it holds profound implications for investors.
A Surprising Loss: Over 5% of Ethereum Supply
In a comprehensive analysis by cryptocurrency researcher Alice Thompson, it was disclosed that a staggering percentage of Ethereum may be permanently inaccessible. Over its decade of existence, missteps and unintended errors have locked away substantial amounts of ETH, raising concerns among enthusiasts and investors alike.

Thompson’s findings highlight that user mistakes, including lost wallets and erroneous transactions, have led to the loss of over 1.1 million ETH, valued at approximately $4.5 billion—representing more than 0.8% of Ethereum’s total supply.
One notable example includes the infamous Parity bug, which rendered 305,000 ETH worthless. Furthermore, a failed smart contract meant an additional 70,000 ETH from another venture became irretrievable, while the Akutars mint mishap locked up another 15,000 ETH. Lastly, an alarming 30,000 ETH is sitting idly in a designated burn address created due to market maneuvers.
Among these sobering instances lies the elusive wallet of Rain Lõhmus, containing 250,000 ETH. The initial investment of just $80,000 in the early days of Ethereum has transformed into a virtually inaccessible digital treasure now worth nearly $1 billion, primarily due to lost key access.
Beyond user-induced losses, Ethereum’s substantial burn rate post-EIP-1559 implementation in 2021 has drastically raised the figures. It is estimated that over 6 million ETH might be permanently unavailable due to these mechanisms, equating to nearly $25 billion in lost dollars and over 5% of the total Ethereum pool.
This estimate does not encompass the numerous instances of lost keys and forgotten wallets connected to Ethereum’s genesis block. Hence, the reality of lost ETH could be significantly higher, painting a grim picture for the community.
When juxtaposed with Bitcoin, which sees an estimated 20% of its supply, currently at a cap of 21 million coins, the intricacies of lost coins differ. Lost Bitcoin holds a more profound impact on its value due to its finite supply, creating a scarcity that isn’t paralleled by Ethereum’s inflating supply.
