Some critics have claimed that a cryptographically relevant quantum computer (CRQC) could one day destroy Bitcoin, The theory is simple, a powerful enough quantum machine could reverse engineer secret private keys from public keys, allowing hackers to steal funds and falsify transactions.
Is this something we have be worried about?
In my honest opinion, I can't say for certain whether or not the threat of a quantum computer destroying bitcoin is real, but one thing is that theres been quite a hype around this subject across social media platforms.
But here is the truth, if it happens that quantum computers are real and the threat against bitcoin is also real, when they finally arrive, I think for most people, there will be much more important things to worry about than worry about bitcoin, for example, banks, governments databases and so on, and this is because whatever can break bitcoin can break anything.
