Five bitcoin wallets dormant since 2014 moved a combined 964.85 BTC, worth approximately $74.8 million at current prices, in a 48-hour window ending May 25, 2026. The movement of such old coins, often referred to as "Satoshi-era" Bitcoin, has analysts pointing to growing security concerns as a potential motive.
"The transfer of such an old wallet coincided with the release of major research and news in the quantum technology sector," CryptoQuant analyst Maartunn noted, referring to a recent Glassnode report on Bitcoin's quantum security. The report highlighted that 30.2%, or 6.04 million BTC, of the total supply is potentially vulnerable to future quantum attacks due to residing in older, less secure address types.
The movement comes as the legal definition of "dormant" Bitcoin is being tested in a New York court. A lawsuit filed by a plaintiff named Noah Doe seeks ownership of 39,069 inactive Bitcoin addresses, characterizing them as abandoned property under New York law. The case has drawn scrutiny for its methods, as plaintiffs sent legal notices to hashed public key addresses (P2PKH) which often hold no value, while the actual BTC sits in unnotified Pay-to-Public-Key (P2PK) scripts, according to Timechain Index founder Sani.
This legal and technical backdrop adds a new layer of complexity to the awakening of long-dormant wallets. While some market watchers fear that such movements could signal an intent to sell, creating downward price pressure, others see it as a prudent security measure. The owners of the recently moved 964.85 BTC may be upgrading their wallets to protect against the long-term threat of quantum computers, which could theoretically derive private keys from the exposed public keys common in early Bitcoin addresses. As IBM targets quantum advantage by the end of 2026, the threat is no longer a distant speculation for long-term holders.
