What happened

A fourth wave of suspected attacks on Coldcard Bitcoin hardware wallets moved about 388.9 BTC in 218 transactions, affecting 462 potential victims, according to Galaxy Research analyst Alex Thorn.

Confirmed

Global impact / market context

Coldcard is a widely used hardware wallet; large‑scale theft raises concerns about security flaws, which could lower user confidence, push holders toward other storage methods, and increase demand for more secure solutions.

Analyst inference

Crypto thefts often create short‑term selling pressure on the stolen coin as assets are quickly moved, while heightened security worries can boost interest in custodial services and security‑focused projects.

Analyst inference

What to watch

1. Any follow‑up statements from Coldcard or its parent about the attacks and possible firmware updates to address the issue. Analyst inference
2. Further analysis of the 218 transactions to see if the stolen BTC is being sent to mixers, exchanges, or other addresses, indicating potential liquidation. Confirmed
3. Regulatory responses or guidance on hardware‑wallet security that could affect compliance requirements for crypto service providers. Analyst inference
