Dormant 2011 Bitcoin wallet moves 49.97 BTC as FalconX-linked routing raises questions

A roughly 15-year-old stash worth about $3.23 million moved after sitting since July 2011, drawing attention to an estimated $10 average acquisition cost and leaving open whether the transfer reflects a sale, custody change or wallet reorganization.

Fact Check
The core claim is verified. The mempool.space on-chain record confirms exactly 50 BTC was sent to SegWit address bc1qlm9x38fe9hr7ncnas295rjjn2t3kyders94mmq, confirmed 2026-08-07, matching the claimed value (~$3.22M) and the fact that the coins still sat in the receiving address. CoinDesk confirms the whale accumulated in 2011 at ~$10/BTC (consistent with 'around $10 to $15'), the ~10-month dormancy framing, and the FalconX-linked deposit history of the receiving address (also tied to Nexo and Prime Trust). CoinNess and BitcoinWorld independently corroborate the 50 BTC / ~$3.22M / 10-month dormancy / FalconX-OTC pattern. A minor framing nuance: CoinDesk emphasizes the origin wallet dormant since 2011 while the aggregators emphasize a 10-month dormancy of the specific cluster movement, but these describe the same event and do not contradict the claim.
Summary

A Bitcoin wallet holding 49.97 BTC received on July 16, 2011 reactivated on Aug. 6, 2026 after roughly 15 years of dormancy, moving a stash worth about $3.23 million, or more than 500 million yen. Galaxy Research said the address had never spent the coins before and had an estimated average acquisition cost of about $10 per BTC, leaving the position with gains of roughly $3.23 million at the time of the transfer. The coins were swept to a fresh address, and Arkham Intelligence later linked activity to a FalconX-labeled wallet. Because FalconX is a crypto prime broker for institutions, the routing may reflect consolidation, custody changes, collateral or trading infrastructure, wallet reorganization, inheritance-related handling, or a review of private key management rather than a confirmed sale. Market participants watch such long-dormant transfers because they can sharply lift Coin Days Destroyed and renew attention on early Bitcoin holdings.

Terms & Concepts
  • Coin Days Destroyed: An on-chain metric, also known as Satoshi Days, that measures how long coins had remained unspent before they moved by multiplying coin amounts by their dormancy period.
  • FalconX: A crypto prime broker that serves trading firms and institutions, so transfers involving its labeled wallets can indicate custody, collateral or trading-related routing rather than a retail sale.
