Bitcoin Wallet Moves $1.7 Million in BTC After 15 Years of Inactivity
A Bitcoin wallet that had remained inactive since May 2011 moved 20.43 BTC worth approximately $1.7 million on September 29, ending more than 15 years of dormancy, according to Galaxy Research.
The transfers were split into two batches of 10.33 BTC and 10.10 BTC. Based on estimated historical acquisition values of about $4 and $3 per Bitcoin, respectively, the movements represent substantial appreciation from their original values.
Galaxy estimated that the larger 10.33 BTC batch had gained approximately $872,000 relative to its historical basis, equivalent to a reported increase of about 2,192,671%. Across the two groups of old Bitcoin outputs, the estimated combined gain was approximately $1.724 million.
The calculations reflect the difference between estimated historical values and current values. They do not establish that the Bitcoin was sold or that the wallet owner realized any of those gains.
Bitcoin Wallet Transfers Leave Ownership Unresolved
Galaxy Research did not identify the sender or recipient associated with the September 29 transactions. As a result, the available blockchain data establishes that the long-dormant Bitcoin moved but does not determine who controlled the coins or why they were transferred.
The transactions also do not, by themselves, demonstrate that the funds were sent to an exchange or that ownership changed hands. Bitcoin can be moved between addresses for a range of reasons, and the transaction data cited by Galaxy does not establish the purpose of these particular transfers.
The movement comes amid a broader series of transactions involving Bitcoin that had remained untouched for many years.
More Dormant Bitcoin Moved in September
On September 5, twelve wallets each holding 50 BTC transferred a combined 600 BTC after more than 16 years of inactivity. The coins originated from mining rewards generated in March 2010 and had an estimated value of approximately $48 million.
Blockchain investigators traced those outputs to newer unidentified addresses but found no evidence establishing that they belonged to Bitcoin creator Satoshi Nakamoto.
Galaxy also tracked four wallets that had been inactive for at least a decade and collectively moved 1,971.03 BTC between September 6 and September 22. Separately, a wallet containing 10.25 BTC ended a dormancy period dating to March 2011.
Another wallet from 2011 transferred 100 BTC worth approximately $8.09 million on September 19. Three days later, an address that had been inactive since July 2012 moved 600 BTC valued at approximately $51.9 million.
The September 29 movement of 20.43 BTC therefore forms part of a wider series of transfers involving long-dormant Bitcoin holdings. However, the transactions alone do not establish a common owner or connection between the wallets.
Bitcoin Recovery Adds Market Context
The dormant-wallet movements occurred as Bitcoin recorded gains through August and September. TradingView data cited in the source showed BTC rising approximately 25% in August and another 9% in September.
Bitcoin also moved above $87,000 for the first time in eight months, with the recovery accompanied by short covering and stronger liquidity.
The market rebound has renewed attention on October's historical performance, often referred to by traders as “Uptober.” From 2013 through 2025, Bitcoin ended October higher in 10 of 13 years, with an average monthly return of about 19%.
That historical performance does not establish what will happen in another October, nor does it explain the decisions behind the dormant-wallet transactions. For the September 29 transfers, Galaxy's findings confirm the movement of 20.43 BTC after more than 15 years of inactivity, while the identity of the owner and the purpose of the transfers remain unknown.
