> 1.) As quantum computing advances, there will be at least one successful 51% attack on a major cryptocurrency.

Is there a quantum solution for one of the popular proof-of-work algorithms?

No, but there is a quantum computer algorithm for classic asymmetric cryptography, which would affect some major proof-of-stake coins if quantum computers ever become practical.

but that wouldn't be a 51% attack, that would just be stealing a wallet
