Between October 6 and 8, 2026, the US government moved roughly 17,795 Bitcoin — about $1.5 billion at prevailing prices — out of seized Bitfinex-hacker wallets and into Coinbase Prime. On-chain evidence points to a routine custody transfer, not a sell-off.

Three Tranches, One Destination: Coinbase Prime
According to an on-chain forensic analysis by btc.network, the funds moved in three distinct tranches. Wallets labeled “US Government: Bitfinex Hacker Seized Funds” by Arkham Intelligence sent the coins in stages toward Coinbase Prime, the exchange’s institutional trading and custody arm. The largest single transaction in the sequence, 12,267 BTC, was recorded in block 970,496 on October 8 — but it landed at unlabeled addresses, not at a recognizable exchange deposit address. That detail matters: an actual liquidation sale would typically route through clearly identifiable exchange hot wallets, not neutral intermediary addresses.
Why Coinbase Prime Isn’t a Coincidence
The destination is no surprise. The US Marshals Service (USMS), the federal agency responsible for managing seized assets, has held a $32.5 million custody contract with Coinbase Prime since July 2024. Coinbase Prime provides institutional clients — from hedge funds to government agencies — with regulated infrastructure for secure storage, trading, and settlement of large crypto holdings. A transfer toward that platform is not a signal of an imminent retail-facing sale; it’s a custodian handoff within the government’s already-established infrastructure.
The Mempool as Forensic Witness
Perhaps the strongest evidence against the sell-off thesis isn’t the transaction trail itself but the state of the Bitcoin network while the transfers were happening. Between October 7 and 9, network transaction fees sat at just 1 to 1.4 satoshis per virtual byte (sat/vB) — a notably low level. At the same time, the mempool, the holding area for unconfirmed transactions, stayed unusually thin, averaging between roughly 0.67 and 1.18 megabytes.
Anyone forced to move large amounts of Bitcoin under time pressure — say, to avoid a forced liquidation — typically pays substantially higher fees to force fast confirmation. Low fees and a thin mempool point instead to a planned operation under no particular time constraint: the opposite of a panicked or forced sale.
Bitcoin’s Price Still Fell — Just Not Because of This
Despite the lack of sell-off signals, Bitcoin’s price fell sharply over the same window: from $85,780 on October 6 to a low of $80,425 on October 8, a 6.3% drop. The cause, however, was not the government transfer — it was a cascade of two unrelated market dynamics.
First, a wave of forced liquidations of leveraged long positions triggered roughly $1.09 billion in selling — a classic domino effect in which falling prices trigger automated margin calls and forced closures among derivatives traders. Second, US spot Bitcoin ETFs saw significant outflows: $484.9 million left on October 7, the worst day since June, followed by another $244.1 million on October 8, including $207.7 million from BlackRock’s IBIT and $197.1 million from Fidelity’s FBTC.
The Recovery as Additional Evidence
The most telling detail may be what happened on October 9: Bitcoin’s price recovered slightly to $82,546, and ETF flows turned positive again — a net inflow of $21.1 million. Had the government transfer genuinely been the prelude to a large-scale sale, it’s unlikely the market would have begun recovering at precisely the moment the largest individual tranches had already been completed. The timing supports the view that market participants did not treat the custody transfer as a bearish signal once the underlying on-chain data became publicly visible.
What This Means for Investors
The episode is a useful lesson in distinguishing on-chain movement from actual market selling. Not every large wallet transaction signals impending sell pressure. Addresses labeled “government” or “seizure” often follow internal administrative and legal processes that have little to do with market logic. Anyone trying to correctly interpret price action should look beyond raw transaction size and also weigh fee levels, mempool load, and the actual transaction destination — an exchange hot wallet versus an unlabeled address.
For the US government, Bitcoin remains one of the largest balance-sheet positions it holds anywhere: even after the October transfers, Washington is still estimated to hold between 320,000 and 328,000 BTC — a position worth roughly $25.5 to $27.5 billion and the largest known sovereign Bitcoin holding in the world.
