I would be quite worried about advances in quantum computers if I had any Bitcoin after watching this DEFCON talk: https://www.youtube.com/watch?v=OkVYJx1iLNs

Quantum is a known threat. There is enough time to fix it. Folks are working on the fixes.

Cryptocurrencies would be the last thing I worry about w.r.t Quantum crypto attacks. Everything would be broken. Think banks, brokerage accounts, email, text messages - everything.

Wonder if this would become the next "nuclear proliferation".

Since it's so hard to manufacture it gets controlled at state level and then becomes a technology that the general public are never allowed to have.

No, it is a known problem. It will get fixed in time.

That based on the assumption that we don't have any quantum breakthroughs
