Current Events > Wouldn't quantum computers essentially break bitcoin and their derivatives?

(+) Yeah! (+)

I really don't see it as a viable thing 2~3 decades from now. I don't see it how they would stay decenteralized when world governments can essentially hack into your money.

Algorand is achieving quantum resistance with state proofs

Lesser blockchains will be broken easily, but it will be a good thing for quantum computing to erase all of the useless coins

No.

Quantum computers can't magically break any encryption that exists. There's just some specific encryption algorithms that, in theory, a quantum computer should be able to crack, many many orders of magnitude faster than a regular one can. Bitcoin's algorithm is probably fucked (though I don't know enough about it to say for sure), but there will certianly be ones out there that are not. But it's not that quantum computers are inherently lightning-fast per se; it's just that certain algorithms have weaknesses that only a quantum computer can exploit (while a regular one cannot).

Well even if some coins apply higher bit encryption I'm sure governments will have enough technological resources to create super quantum computers to break those too.

Ok, lol, what did you do on Friday night in 2004

And did you have Cartoon Network
