I'm more concerned that so many people have been looking for some kind of weakness in BTC for so many years and it always ends up on quantum computers that at this point don't have even 1% of the power needed to do something like smash BTC into pieces.
Bitcoin will definitely be a serious target.
The US states and big companies like Tesla, MSTR, and El Salvador have large bitcoin reserved. They would care deeply if quantum attacks becomes a threat. Imagine national reserves being stolen what will happen to the nations economy. If billions in Bitcoin is lost due to quantum theft, it will reduce the trust in digital assets globally.
Why don't you write how much BTC they have and which US states - and how much does the Mr. Mars company and El Salvador have? Roughly speaking, it seems to me that they have a maximum of 20 000 BTC together (El Salvador has a little over 6000). I think you're worrying about completely unrealistic and pointless things - but if you have nothing else to worry about, that's your choice

I see no danger to Bitcoin anytime soon.The meme about quantumQuantum computers having the ability to break bitcoin has been a meme for as long as quantum computers have existed.
And it is overhyped.Nobody seems to talk about how the quantum computers that we have are glorified gimmicks that may probably have reached a dead end.
Decoherance of superpositionsIt is not physically possible
for coherent superposition to be scalable
beyond a certain macroscopic threshold, to the level needed to break Bitcoin
either beyond a certain scale, as by the uncertainty principle
, which. Which is not just an engineering issue but a
physical lawphysics issue.
Roger Penrose, a nobel prize winning physicist, has even written a paper on this. [1]Quantum computing researchers are hoping to discover new
, unexplored physical laws that favor a workaround for
quantum computinglarge scale decoherence. That is their
biggest gamblegambit.
[1] gravity collapses quantum states at the macroscopic threshold, preventing large-scale superpositions
