Galaxy Research says losses tied to the Coldcard hack could reach as much as $130 million, an estimate that puts fresh scrutiny on supply-chain and device-trust risk for Bitcoin holders who rely on hardware wallets for self-custody.
Galaxy Research says losses tied to the Coldcard hack could reach as much as $130 million, an estimate that puts fresh scrutiny on supply-chain and device-trust risk for Bitcoin holders who rely on hardware wallets for self-custody.
What Galaxy Research Is Claiming About the Coldcard Hack
The $130 million figure comes from Galaxy Research, which framed the number as a potential loss tally connected to the Coldcard incident rather than a fully confirmed, realized total. For related coverage, see Tether Reserves Shrink as Market Losses Weigh on Q2 Results.
It is important to read the number as an upper-bound estimate. The available research treats this as a developing security story, and the figure reflects possible exposure, not an audited accounting of stolen funds.

The evidence supporting this story is only partially verified. Readers should treat the loss estimate as an attributed claim from a single research desk that still requires independent confirmation.
Why a Coldcard Breach Matters for Bitcoin Self-Custody
Coldcard is a Bitcoin hardware wallet, and any credible attack on such a device strikes at the core promise of self-custody: that keys generated and stored on the device stay secret. Coinkite, the maker of Coldcard, has previously published a seed-generation warning relevant to how wallet keys are produced.
The concern here is wallet-level and supply-chain risk, not a weakness in the Bitcoin network itself. Reporting indicates the flaw let attackers guess Bitcoin wallet keys generated under certain conditions, a device issue distinct from Bitcoin’s underlying protocol.
That distinction matters for holders weighing whether the incident affects them. The exposure documented so far centers on how affected devices produced keys, an issue that has been tied to a vulnerability enabling Bitcoin theft rather than to broad on-chain compromise.
Early reporting has also suggested the breach touched a meaningful number of wallets, with one account describing an impact across more than 1,000 Bitcoin addresses. The precise scope of realized damage remains unsettled.
What Still Needs Confirmation
Several key facts remain open. The number of affected users and devices, the exact attack path, and the split between realized versus merely possible losses are all unconfirmed in the current evidence set.
Stronger confirmation would require direct company disclosures, forensic findings, or verified on-chain accounting that traces stolen funds. Until those arrive, the loss estimate should be read as a ceiling under investigation, not a settled outcome.
The research behind this story was incomplete, so the article deliberately avoids regulatory, legal, or market-outlook claims. The next concrete signals to watch are official statements from Coinkite and any updated loss accounting from Galaxy Research or independent analysts.
