Stacks Co-founder Shares Lessons from Coldcard Security Incident: Don't Put All Your BTC in One Basket

Odaily News, Stacks co-founder Muneeb shared his views on the Coldcard wallet incident, summarizing lessons learned in three areas: Bitcoin storage strategy, quantum computing threats, and ecosystem security building. Regarding Bitcoin storage strategy, he noted that many industry security experts are not even familiar with Coldcard, and top-tier security research institutions may not have conducted thorough audits of its code. Muneeb believes the best approach going forward should be asset diversification rather than concentrating all funds in a single solution, and suggested:

1. Allocate 20%-30% of BTC to ETFs, such as BlackRock's Bitcoin ETF IBIT, for professional custody and regulatory protection;

2. Allocate 40%-50% of BTC to multisignature solutions like Casa, such as the three-key model, spreading keys across security companies, mobile devices, and hardware wallets;

3. Allocate 20%-30% of BTC to more advanced self-custody approaches, combining different hardware wallets and diverse entropy sources.

On the quantum computing threat, Muneeb stated that once quantum computers break through existing encryption systems in the future, Bitcoin users may experience a shock similar to "BTC suddenly being transferred out of cold wallets." The quantum threat is real, and the industry should prepare in advance rather than underestimate technological progress, especially against the backdrop of large language models accelerating scientific research breakthroughs.
