A bitcoin address that had not signed a transaction since 2013 moved its entire balance of 411.45 BTC on Sunday, a holding now valued at roughly $34 million. The coins were originally acquired when the asset traded around $131, meaning the position has appreciated more than 600-fold while the owner never bought, sold, or transferred a single unit.
The move fits a pattern of historic supply shifting
Blockchain analytics firm Arkham Intelligence flagged the transfer, which occurred at 18:23 UTC. The destination was a fresh SegWit address, and the fee amounted to 337 satoshis, a fraction of a cent. The funds have not touched an exchange, and the new wallet has yet to initiate any outgoing activity. Arkham notes that similar awakenings occurred earlier this month: two decade-old addresses moved a combined 417 BTC a day prior, and another pre-Covid whale migrated its stack the week before. The clustering mirrors the sporadic mega-whale activity seen throughout 2025.
Custodial hygiene, not a liquidation signal
Each of those earlier movers also routed coins to new private wallets rather than trading venues. That pattern, upgrading from legacy address formats to modern P2WPKH standards, points to routine security maintenance. Long-term holders often execute such migrations to reduce future transaction costs and improve custody hygiene before any eventual financial decision. The absence of exchange deposits suggests the market is not about to absorb a sudden influx of vintage supply.
Thirteen years of noise and one decision
The original wallet received its principal deposit on Sept. 11, 2013. Over the subsequent 13 years it accumulated dozens of dust deposits, many from addresses Arkham labels as phishing attempts. The technique, known as address poisoning, tries to trick owners into copying a scammer’s address from their transaction history. The holder never fell for it. The sole signed transaction in over a decade was Sunday’s migration to a cleaner, cheaper, more secure format.
