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

According to Odaily Planet Daily, a16z stated in his latest article on quantum attacks that Bitcoin faces two major real-world challenges, making a shift towards 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 controversial issue could trigger a destructive hard fork.

Secondly, there's the issue of the initiative in migration. Bitcoin's transition to quantum-resistant signatures cannot be passive; holders must actively migrate their assets. This means a large number of dormant cryptocurrencies vulnerable to quantum attacks will lose their protection. It's estimated that millions of such quantum-vulnerable Bitcoins, potentially abandoned, are worth hundreds of billions of dollars at their current market capitalization.
