TLDR
Bitcoin (BTC) is trading just below $64,000, holding firm even as a major Coldcard hardware wallet exploit drains significant BTC from affected users.
- BTC has rebounded to the low $64,000 area with modest daily gains, despite selling by large holders and ongoing wallet security headlines.
- A Coldcard firmware bug let attackers brute-force wallet seeds, with estimated losses in the $70$88 million range, but Bitcoins protocol itself remains intact.
- Market reaction is contained so far; the bigger impact is on self-custody confidence, while traders watch key support near $62,000$63,000 and any further exploit waves.
Deep Dive
1. BTC Price Near $64K
Recent data shows Bitcoin around $63,800 to $64,000, up slightly on the day with around $25 billion in 24-hour volume.
One detailed market update reports BTC rebounded above $63,000, briefly hitting $64,117 before settling near $63,545, a roughly 1.6 percent gain over 24 hours, even as corporate holder Strategy sold 1,638 BTC for about $104.7 million in the prior week and miners offloaded roughly 1,774 BTC for around $112 million. That move is documented in a crypto market recap.
Another review notes BTC trading near $64,000 in Asian hours, up about 2 percent over 24 hours and around 1 percent on the week, with traders focused on whether it can hold above $63,000 after several failed attempts, according to a Coindesk market piece.
Despite negative headlines, BTC is still in a relatively tight range rather than breaking down, suggesting broader demand and macro factors remain more important than one wallet-brand crisis.
2. What The Coldcard Hack Actually Is
The Coldcard incident is a hardware wallet failure, not a breach of the Bitcoin network.
Multiple investigations show a bug in Coldcard firmware dating back to March 2021 replaced the intended hardware random number generator with a predictable software substitute. This sharply reduced the randomness of seed phrases, allowing attackers to precompute seeds and sweep funds from vulnerable wallets. One technical analysis estimates 1,367.05 BTC, about $88.6 million, stolen across 4,585 addresses, making it the largest confirmed hardware wallet hack in Bitcoin history, as described in a PRNG vulnerability report.
Another long-form summary reports an attacker drained about $70 million from roughly 1,200 Coldcard wallets in forty minutes by reproducing predictable seeds, with around $30 million taken in the first ten minutes, based on a wallet security explainer.
Bitcoin investor Anthony Pompliano has publicly stressed that Bitcoin was not hacked and that the failure sits entirely in Coldcards seed-generation design, not in Bitcoins consensus rules or ledger, in a clarifying article.
The exploit targets how some Coldcard devices generated keys, not Bitcoin itself, but it is a serious reminder that self-custody depends on the quality of your wallets firmware and entropy, not just being offline.
3. Market Reaction And What To Watch
So far, the Coldcard hack has not triggered a broad BTC crash. Reports show many affected users and long-dormant wallets moving coins, sometimes to exchanges, as they migrate away from vulnerable seeds, but price has stayed in a 62,000 to 65,000 range.
Market commentators highlight that traders are looking past the latest Coldcard sweep and focusing more on macro data and ETF flows. One analysis warns that if BTC fails to clear resistance near 65,000 before key US jobs data, a drop below roughly 62,000 could open a path toward 60,000, whereas softer labor numbers could support a break higher, as outlined in a macro-linked BTC outlook.
For Coldcard users, official guidance emphasizes generating a completely new seed on fixed firmware and migrating funds; firmware updates cannot repair already-weak seeds. For the wider market, the bigger shift may be psychological, pushing some holders toward multisig setups, diversified hardware, or custodial products such as spot ETFs.
For BTC price, this looks more like a localized security shock than a structural break. The key signals to monitor are whether exploit waves continue, whether self-custody confidence erodes further, and how BTC behaves around the 62,000 to 63,000 support zone.
Conclusion
Bitcoins resilience near $64,000 suggests that traders are differentiating between a serious Coldcard wallet exploit and the underlying BTC asset.
The Coldcard bug has produced tens of millions in losses and shaken self-custody confidence, but it has not yet changed Bitcoins broader range or narrative, which remains driven by macro conditions, institutional flows, and key technical levels. If exploit activity fades and macro data stay supportive, the impact may be remembered as a hardware wallet cautionary tale rather than a defining market regime shift.
