A Bitcoin wallet that had remained inactive since 2013 transferred its entire balance of 411.45 BTC on Sunday, according to blockchain data from Arkham Intelligence cited by CoinDesk. At the price referenced in the report, the holdings were worth roughly $34 million, compared with about $54,000 when most of the coins were acquired.
A 13-year-old balance changes address
The wallet received around 411 BTC on Sept. 11, 2013, when Bitcoin was trading near $131. The owner then left the balance untouched for more than a decade. There were no purchases, sales or transfers from the holder during that period, despite Bitcoin passing through several major market cycles.
The coins remained in place through three Bitcoin halvings, the cryptocurrency’s 2017 market boom, the 2022 collapse of FTX and the launch of spot Bitcoin exchange-traded funds in 2024. Based on the values cited in the report, the holdings increased more than 600-fold from their original value.
On Sunday at 18:23 UTC, the owner sent all 411.45 BTC to a new address. The transaction fee was 337 satoshis, a very small fraction of one Bitcoin. The destination has received no other funds and has not made an outgoing transaction, according to the available blockchain data.
The wallet did show minor activity over the years in the form of dozens of deposits worth less than $1 each. Several of those transactions came from addresses identified by Arkham as phishing-related. Such deposits are associated with “address poisoning,” a scam technique in which attackers send small amounts of cryptocurrency to a wallet in the hope that its owner later copies a fraudulent address from the transaction history.
Transfer does not yet indicate a sale
Large movements from wallets that have been inactive for many years often attract attention because observers may interpret them as preparations to sell. In this case, however, the Bitcoin has not been sent to a cryptocurrency exchange. It remains in a new private wallet, which limits the evidence for an immediate market sale.
The move also changed the format of the wallet address. The original wallet used an older address type, while the receiving wallet uses SegWit, or P2WPKH, a more recent Bitcoin format. SegWit addresses can provide security and transaction-fee advantages compared with older formats.
That change has led to the interpretation that the transaction may represent custodial maintenance or a security upgrade rather than an imminent disposal of the coins. The wallet’s lack of further activity means the eventual purpose of the transfer remains unknown. Blockchain data can show where coins move, but it does not identify the owner or establish why a transfer was made.
Part of a wider movement of old Bitcoin
Sunday’s transaction was not an isolated example of long-dormant Bitcoin becoming active. One day earlier, two wallets that had been inactive for more than 10 years transferred a combined 417 BTC. The previous week, another large wallet that had remained static since the period before the Covid-19 pandemic also moved its funds.
The pattern resembles activity seen in 2025, when several very large Bitcoin holders moved coins after extended periods of inactivity. Those transfers generated speculation about possible selling, although the reported movements generally sent the assets to new private wallets rather than directly to exchanges.
For the market, the significance of dormant-wallet activity depends on what happens next. A transfer between private addresses does not by itself increase the amount of Bitcoin available for immediate sale. A later deposit to an exchange would provide a clearer indication that the holder may be preparing to trade, while continued inactivity would be more consistent with a wallet migration or security-related change.
