It sounds like you're saying a good quantum computer would enable a 51% attack. Instead, you could glean one wallet at a time, but not use it to somehow "over-power" the rest of the network: https://en.bitcoin.it/wiki/Quantum_computing_and_Bitcoin

Besides, if a cryptocurrency was vulnerable to quantum computing its value would drop as everyone watched QC get closer and closer to viability. Unless someone advances QC technology in secret the market cap of a coin will never be large enough to pay for cracking it.

Bitcoin could change it’s algo to a QC resistant one in advance.
