Bitcoin Wallet Dormant Since 2011 Moves $3.2 Million Toward FalconX-Linked Address

A bitcoin wallet that received 49.97 BTC in July 2011, when the cryptocurrency traded near $10 and had only recently reached parity with the U.S. dollar, sprang back to life on Thursday, moving nearly 50 BTC worth approximately $3.2 million to a SegWit address with prior ties to institutional crypto brokerage FalconX.

The 50 BTC remained in the receiving address as of Friday morning, but that wallet has previously sent funds to FalconX-labeled deposits, leaving open whether the old stash is being reorganized or moved closer to a trading venue. FalconX is one of the largest institutional crypto prime brokerages by trading volume, serving hedge funds, asset managers, and other large counterparties.

Transaction Details

According to Galaxy Research, the wallet originally received the coins on July 16, 2011, and had not spent them since. The 49.97 BTC position survived more than a decade of bitcoin booms, crashes, and exchange failures — including the 2014 collapse of Mt. Gox, then the world's largest Bitcoin exchange — before this week's transfer.

The transaction, included in block 961331 at 20:14 UTC on Aug. 6, combined four inputs from the dormant address totaling 49.97 BTC with two smaller inputs from other addresses. Exactly 50 BTC was sent to a SegWit address, while a second output received approximately 0.00116 BTC after fees.

SegWit is a newer Bitcoin address format that makes transactions more space-efficient and generally cheaper to process. Addresses beginning with bc1 use this format.

Destination Address History

The destination is not a fresh wallet. Arkham data show the address has been active for several years and previously sent 6.336 BTC and 16.131 BTC to addresses the analytics platform labels as FalconX deposits. It has also received funds from wallets Arkham identifies as a Nexo hot wallet and Prime Trust custody.

The newly arrived 50 BTC remained in the address as of Friday morning, meaning there is no on-chain evidence that the dormant coins themselves have been sent to FalconX, another exchange, or sold.

Dormant wallets from bitcoin's earliest years tend to attract attention when they move because their owners accumulated coins when the asset was worth a fraction of today's price. Blockchain analytics firms and on-chain trackers routinely flag these movements, which can generate discussion among traders even though the on-chain data alone does not reveal intent. Movement can reflect anything from wallet upgrades and custody changes to preparations for a sale.

Coldcard Exploit Context

The transfer comes amid heightened security concerns following one of the worst cold-wallet exploits to hit Bitcoin in years. Coinkite, maker of the Coldcard hardware wallet, urged users on Tuesday to move funds after disclosing a flaw in firmware dating to 2021 that could expose keys generated by affected devices. Attackers have swept as much as $114 million from vulnerable wallets since July 30, according to the company, in four waves of thefts.

There is no evidence linking the 2011 wallet to the Coldcard issue — the address predates the device by years. However, the disclosure has prompted long-term holders to reexamine old storage setups, adding another possible reason for dormant bitcoin to suddenly move on-chain. The incident serves as a reminder that coins can sit safely for more than a decade and still become vulnerable when the software protecting their keys fails.
