Stacks founder urges BTC holders to spread storage across ETFs, multisig, and multiple hardware wallets

Stacks founder Muneeb Ali said in a post on X that the recent Coldcard security incident offered three major lessons for the Bitcoin market: how BTC should be stored, how seriously the industry should treat quantum-computing risks, and what needs to change in Bitcoin ecosystem security. He said the incident affected many long-term Bitcoin holders who prioritize security and choose self-custody, and argued that users should avoid placing all of their assets in a single setup. Instead, he recommended diversifying exposure through a mix of ETFs, multisignature arrangements, and different hardware wallets. Ali also said quantum computing poses a real threat to cryptographic systems, adding that the rise of large language models is accelerating scientific breakthroughs and that preparation is better than underestimating the pace of development. On ecosystem security, he called for closer cooperation between the Bitcoin ecosystem and outside security research organizations, warning against security-resource isolation tied to a “Bitcoin-only” mindset and urging more security experts to participate in BTC ecosystem building.
