Coldcard Mk3 Warning: Move Your Bitcoin Now

Hardware wallet manufacturer Coinkite has issued an urgent advisory for users of the Coldcard Mk3 model. The company suggests that anyone who generated their recovery seed on certain firmware versions should transfer their Bitcoin to a new, secure wallet immediately.

The alert follows reports of security researchers identifying a suspicious transfer of nearly 600 Bitcoin. This movement, totaling over 38 million dollars, has sparked debate regarding the safety of older hardware iterations. While no direct proof links this specific wallet model to the large outflow, the company is prioritizing caution to protect user funds.

For now, the focus remains on personal asset safety. If you use a Coldcard Mk3, verify your firmware and follow the company instructions to move your assets to a fresh seed. Keeping your private keys offline and updated is the best way to avoid unnecessary risk in this market.
