Do you think quantum computers would break Bitcoin's security?

You'll know once a quantum hack is underway when all banks lose their account balances, and all military secrets are disclosed. BTC loss will be the least of your problems

I don't think the NSA would want to kill any banks/sponsors...The NSA will be the first to have one since their resources are endless....so the NSA will destroy what they think it's fair to do so...bitcoin included

In theory, a powerful enough quantum computer could bruteforce anything. But right now this is science fiction and a non issue. This is something the future generation 100s of days from now will have to deal with.

No, I don't think that's true. There are mathematical problems that are complex enough that even quantum computers wouldn't make a difference to them.
