A batch of 100.02 Bitcoin mined in July 2010 moved to two new addresses on October 7 for the first time in 16 years, according to blockchain analysis. The coins were worth approximately $8.3 million at the time of movement, based on Bitcoin trading near $83,000.
The batch consisted of two separate mining payouts: 50.02 BTC mined on July 26, 2010 in block 70,522, and 50 BTC mined on July 28, 2010 in block 70,748. The two payouts were merged into a single transaction on July 30, 2010, and remained untouched until October 7, 2025, when they were split into two modern addresses: 10 BTC sent to one address and 90.02 BTC to another. The transaction paid a fee of 1,467 satoshis, valued at approximately $1.22.
Galaxy Research, a blockchain analysis firm, confirmed the dormancy period and the coin-level tracking. “We maintain a complete ledger of every single UTXO and all their historical movements (about 1.7 terabytes). This address has been somewhat active in the past, but these specific coins have not moved since 2010. We track the coins,” Galaxy Research stated.
The coins belong to the category of Satoshi-era Bitcoin, named after the pseudonymous network creator Satoshi Nakamoto. When mined in July 2010, the 100.02 BTC batch was worth approximately $29 based on Bitcoin’s highest registered price that year. The mining reward has been halved four times since 2010, most recently to 3.125 BTC in April 2024.
Recent Dormant-Wallet Activity
The October 7 movement is part of a broader wave of Satoshi-era coin activity. In February 2025, a 50 BTC batch moved after approximately 15 years of dormancy, valued at around $5 million at the time. In August 2025, a 49.97 BTC batch moved to a wallet labeled FalconX by the Arkham blockchain analytics platform. Between August 16 and 26, 2025, six wallets moved a combined 553.59 BTC, valued at approximately $40 million. Two of those six wallets carried tags tied to a New York lawsuit involving 39,069 dormant addresses.
Transaction Details and Interpretation
The coins were transferred to bc1q addresses, a format that did not exist when the coins were mined in 2010. Moving coins between addresses does not confirm a sale or transfer of ownership; the coins may have been moved between addresses controlled by the same entity. Galaxy Research clarified that while the address has been active in the past, these specific coins had not moved since 2010, distinguishing coin-level tracking from address-level activity.
The dormancy period of 16 years makes this batch among the oldest Bitcoin in active circulation. For context, Bitcoin’s network confirms transactions roughly every 10 minutes, meaning the October 7 transaction was confirmed within minutes of broadcast.
