A 2011 bitcoin wallet moved 50 BTC. Where it went next is the part nobody can confirm
A wallet untouched since July 2011 sent 49.97 BTC — about $3.2 million — into an address that has previously deposited coins with brokerage FalconX, though the funds have not moved again.
An address that received 49.97 BTC on July 16, 2011 — when bitcoin traded around $10, per Galaxy Research, cited by CoinDesk — spent those coins for the first time on Thursday. The transaction landed in block 961331 at 20:14 UTC on Aug. 6, combining four inputs from the dormant address with two smaller inputs from elsewhere. Exactly 50 BTC went to a SegWit (bc1) address; a second output took roughly 0.00116 BTC as change after fees. CoinDesk valued the stack at about $3.2 million, which implies a bitcoin price near $64,000.
The destination is not a fresh wallet. Arkham data cited by CoinDesk show it has been active for years and has previously sent 6.336 BTC and 16.131 BTC to addresses Arkham labels as FalconX deposits, and has received funds from wallets it labels as a Nexo hot wallet and Prime Trust custody. As of Friday morning, the 50 BTC was still sitting there. There is no on-chain evidence the coins have reached FalconX, any other venue, or a buyer.
The timing sits against a separate story. Coinkite, which makes the Coldcard hardware wallet, disclosed a flaw on Tuesday in firmware dating to 2021 that could expose keys generated by affected devices, and told users to move funds. The company says attackers have swept as much as $114 million from vulnerable wallets since July 30, across four waves. Nothing links the 2011 address to that flaw — it predates the device.
Key facts
- 49.97 BTC received July 16, 2011, unspent since; bitcoin ~$10 at the time (Galaxy Research, via CoinDesk).
- Spent Aug. 6, 2026, block 961331, 20:14 UTC; 50 BTC out to a bc1 address, ~0.00116 BTC change (CoinDesk, citing the on-chain transaction).
- Value about $3.2 million (CoinDesk).
- Destination previously sent 6.336 BTC and 16.131 BTC to FalconX-labeled deposits; received from Nexo- and Prime Trust-labeled wallets (Arkham, via CoinDesk).
- Coldcard firmware flaw disclosed Tuesday; up to $114 million swept since July 30 in four waves — figure from Coinkite, the vendor (via CoinDesk).
The real-world read
The headline does work the chain does not. "Toward a FalconX-linked address" describes a hop to a wallet that once touched FalconX-labeled deposits — not a deposit, not a sale, not a confirmed counterparty. Those labels are Arkham's clustering heuristics; neither FalconX, Nexo nor Prime Trust confirmed anything, and the report gives no dates for those earlier flows, so the "institutional" read rests entirely on undated third-party tags.
The $114 million theft total comes from Coinkite — the company whose firmware failed, sizing its own incident with no independent verification cited. Treat it as a vendor estimate.
And the genre itself deserves discounting: one 50 BTC spend, sitting still. CoinDesk says as much — movement can mean a wallet upgrade, a custody change, or a sale. Which one is unknown.
Opinion, and whose
CoinDesk's framing is that the Coldcard disclosure has pushed long-term holders to revisit old storage, giving dormant coins a reason to move. That is the outlet's inference, not an established cause here.
