Jack Mallers: Urges Coldcard bitcoin users to secure funds immediately — Coldcard bitcoin users advised to act now

Jack Mallers, founder and CEO at Strike, is calling on users who generated their bitcoin seed on a Coldcard device to move their bitcoin immediately.

He advises users to inform friends and family about the potential risk and assures that the Strike team is available to help anyone who needs assistance, regardless of customer status.

But we saved everything 🙂.

Earlier this week, Mallers urged Coldcard wallet users to take immediate action following a major bitcoin security incident, according to a previous report. Mallers has also worked to expand Strike’s product offerings, introducing bitcoin-backed loans designed to eliminate liquidation risk. His recent guidance follows earlier security concerns brought to light within the Coldcard user community.
