1feexv6bahb8ybzjqqmjjrccrhgw9sb6uf: Public Key Updated

Bitcoin uses a system of asymmetric cryptography. A user generates a random , which is then mathematically transformed into a public key . This public key is then hashed twice (first with SHA-256, then with RIPEMD-160) to create a shorter public key hash . This final hash is what is encoded into the Bitcoin address you see, such as 1FeexV... .

: The funds are widely believed to be stolen property from the 2011 Mt. Gox hack .

The address is a hashed representation of a public key . The actual raw public key for this address remains unrevealed on the blockchain. 1feexv6bahb8ybzjqqmjjrccrhgw9sb6uf public key

The digital trail went cold from there. The address received its massive balance on March 1, 2011, and has, with eerie stillness, . For over fifteen years, this stash of nearly 80,000 BTC has remained untouched, a ghost holding that represents roughly 0.40% of the total Bitcoin supply.

: 1FeexV6bAHb8ybZjqQMjJrcCrHGW9sb6uF is a legacy P2PKH address. It is not a public key itself; rather, it is a cryptographic hash (specifically a SHA-256 followed by a RIPEMD-160 hash) of the uncompressed public key, encoded in Base58Check format. Bitcoin uses a system of asymmetric cryptography

The 1Feex wallet is a standard legacy address, dictated by the starting digit "1". In a P2PKH script, the transaction locks the cryptocurrency not to the public key itself, but to a double-hash of the public key.

This specific address is famous in Bitcoin history. Let me explain: This final hash is what is encoded into

On March 1, 2011, a single transaction transferred into this address.

The 1feexv6bahb8ybzjqqmjjrccrhgw9sb6uf public key uses advanced cryptographic algorithms to secure transactions and protect user identities. When a user sends a Bitcoin transaction to this public key, the transaction is verified and recorded on the Bitcoin blockchain, ensuring that the transaction is secure and irreversible.

The wallet's notoriety has made it a prime target for cybercriminals. In July 2025, BitMEX Research flagged a sophisticated phishing attack targeting the wallet. The attackers sent a transaction to the 1Feex address using Bitcoin's OP_RETURN function, which allows for up to 80 bytes of arbitrary data to be embedded in a transaction. The message contained a link to a fraudulent website that claimed the address was "lost or abandoned" and attempted to trick visitors into revealing personal information.
