Do you have any other suggestions other than selling and exiting the market? people with access to Quantum Computers have more concerning issues than just hacking Bitcoin addresses, with the probability of breaking the encryption of strong algorithm, other important things are at stake, like military related encrypted data.
I totally agree. Every time I read something about quantum computers it looks like they are being developed just to disrupt bitcoin, that's pretty much the only thing they're useful for. No one ever mentions all the other risks such as military information, national security, nuclear codes, power plants, etc. It's an interesting way to see things.
