Stacks Co-Founder Summarizes Coldcard Security Incident Lessons: Don't Put All Your BTC in One Basket

Comparing news, Stacks co-founded Muneeb expressed opinions on the Coldcard wallet incident, summarizing the three lessons of Bitcoin storage, quantum computing threats, and ecological security construction. In terms of Bitcoin storage strategies, it was pointed out that many industry security experts don't even understand Coldcard, and top security research institutes may not have fully audited its code. Muneeb believes that the best solution for the future should be to spread assets rather than concentrating all funds in a single solution, and suggests:

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

2. 40%-50% of BTC uses a multi-signature scheme similar to Casa, such as the three-key model, to distribute keys to secure companies, mobile devices, and hardware wallets;

3. 20%-30% of BTC is used for more advanced autonomous management solutions, combined with different hardware wallets and different entropy sources.

In response to the quantum computing threat, Muneeb said that after quantum computers break through the existing encryption system in the future, Bitcoin users may experience an impact similar to “the sudden transfer of BTC in a cold wallet”. The quantum threat is real, and the industry should prepare in advance rather than underestimate technological progress, especially in the context of big language models accelerating scientific breakthroughs.
