Coldcard Bitcoin Theft Exceeds $100M: Galaxy Warns of Fourth Wave

Coldcard Breach: Over $100M in BTC Stolen Across Three Waves

Galaxy Research has identified a series of thefts targeting users of Coldcard, a popular hardware wallet for Bitcoin, totaling more than $100 million. The attacks unfolded in three distinct waves, with the latest raising concerns that a fourth wave may already be underway. According to the research, if the pattern continues, cumulative losses could reach approximately $130 million.

Coldcard is widely regarded as one of the most secure options for storing Bitcoin offline, which makes these thefts particularly alarming for the crypto community. The devices are designed to keep private keys isolated from internet-connected systems, yet the attackers have found ways to compromise the security, likely through sophisticated social engineering or supply-chain interference. The fact that such a trusted device has been breached highlights the evolving nature of threats in the digital asset space.

Notably, the stolen Bitcoin has not been moved or spent in any significant way. Galaxy reports that 90% of the funds remain in the attacker's wallets, which could indicate a strategy of holding the assets for future use or waiting for a more opportune time to launder them. This behavior also complicates recovery efforts, as the funds are not being actively traded or sent to exchanges where they might be frozen.

Why the Coldcard Attacks Are a Wake-Up Call for Hardware Wallet Users

Attack Vectors: How Coldcard Security Was Bypassed

While the exact method of compromise has not been fully disclosed, security analysts point to several plausible vectors. One is the possibility of compromised firmware or malicious software updates, where attackers intercept the update process to inject malware. Another is physical tampering during the supply chain, where devices are altered before reaching the end user. Additionally, phishing attacks that trick users into revealing their seed phrases or entering them into a fake interface could have played a role.

These scenarios underscore a fundamental principle in crypto security: hardware wallets are not infallible. Even the most robust device can be undermined if the user is tricked into exposing their keys or if the device is compromised before it arrives. For traders and long-term holders, this means that relying solely on a hardware wallet without additional checks—such as verifying the device's authenticity and using a passphrase—may not be sufficient.

Market Reaction: BTC Price Impact and Investor Sentiment

The news of the theft has not caused a major price swing in Bitcoin, but it has added to the underlying anxiety among investors. The crypto market is already sensitive to security breaches, and the fact that a premium device like Coldcard was compromised could lead to a short-term dip in confidence. However, the broader trend in 2025 has been driven by macroeconomic factors and institutional adoption, so the impact on price is likely to be muted unless the thefts escalate significantly.

For traders, this event serves as a reminder to diversify storage methods and stay informed about security practices. The current BTC price remains above key support levels, but any negative headlines can trigger volatility. Monitoring technical indicators like moving averages and RSI can help traders gauge whether sentiment is shifting.

Key Levels to Watch: BTC Price and Coldcard's Reputation

From a market perspective, the focus remains on Bitcoin's price action. The $100,000 level is a psychological barrier that has been tested multiple times. If the theft news creates selling pressure, a break below the $95,000 support could open the door for a deeper correction. On the upside, a close above $105,000 would signal renewed bullish momentum.

Beyond price, traders should watch how the Coldcard community and the broader hardware wallet market respond. If Coldcard issues a firmware update or offers a detailed post-mortem, it could restore some trust. Conversely, if the attacks continue, alternative hardware wallets like Ledger or Trezor might see increased demand, potentially affecting their market share.

What This Means for Traders: Security and Risk Management Lessons

For traders, the Coldcard incident is a stark reminder that asset security is as important as market analysis. Even if you are not a Coldcard user, the lessons apply to any hot or cold storage solution. The first takeaway is to never enter your seed phrase on any digital device, including a computer or phone, as this can expose it to malware. Second, always verify that your hardware wallet is genuine and has not been tampered with—check for security seals and use official channels for purchases.

Another critical aspect is the concept of “not your keys, not your crypto.” This theft shows that even when you hold your own keys, there are still risks. Diversifying storage across multiple wallets and using multi-signature setups can reduce the impact of a single point of failure. For beginners, understanding these basics is essential, and resources like the trading classroom can provide a solid foundation.

Finally, traders should consider the broader implications for the crypto ecosystem. High-profile thefts often lead to increased regulatory scrutiny, which could affect market liquidity and trading conditions. Staying updated with community discussions in signal rooms can help you anticipate such shifts and adapt your strategy accordingly.
