a16z: "Inefficient governance" and "dormant tokens" are two major problems that pose a more severe quantum threat to BTC.

According to a16z's latest article on quantum attacks, Odaily reports that Bitcoin faces two major real-world challenges, making its transition to quantum-resistant digital signatures imperative. First, there's the issue of governance efficiency; Bitcoin's upgrade process is extremely slow. If the community cannot reach a consensus on a solution, any contentious issue could trigger a destructive hard fork. Second, there's the issue of proactive migration; the transition to quantum-resistant signatures cannot be passive; holders must actively migrate their assets. This means a large number of dormant, quantum-vulnerable coins will lose their protection. It is estimated that millions of such quantum-vulnerable and potentially abandoned Bitcoins exist, worth hundreds of billions of dollars at their current market capitalization.
