With the development of technology, quantum computers will develop further in the future and may threaten the current bitcoin. But don't forget that Bitcoin is also constantly evolving, with developers working tirelessly to maintain and improve bitcoin protocol . So if at some point quantum computers could threaten bitcoin, developers will have a solution to deal with it.

All I’ve seen so far is SegWit and Taproot — and honestly, what did we get? No real scalability, no proper smart contracts.
Sure, maybe quantum computing isn’t here yet, but I’ve also seen how miners react to forks. I wouldn’t bet on the network jumping up to fix things overnight if there’s ever a real quantum threat

Miners are mostly after profit, so they will mine what brings in more profit. After all, someone is still mining BCH today, right?

I’d say even more — BCH could easily break back into the top 10. It handled this year way better than a lot of big altcoins and keeps pushing up the ranks. Would be interesting to see what’s really behind this rise.

Quantum computing "may" break what we have today, but we can always move to another chain, which would mean we would be protected anyways. The only issue is, I have no idea how the old ones would be protected, think about it, we have so many wallets with bunch of bitcoins in it, and some of them are untouched for 10+ years, could be either one issue like that guy who cashed out 80k bitcoins, come back after many years, or it could be someone who forgot their keys.

Good point — the 80K BTC case grabbed headlines, but honestly, this year there’s been a bunch of old wallets moving smaller amounts too. People cashing out coins they’ve been holding for a decade.

Makes you wonder if these OG holders are starting to get spooked by the whole quantum computing risk too

It's really funny that people are afraid of bitcoin becoming obsolete due to quantum computing, but forget how their money is stored.

How do you think your online passwords are protected on servers? How does a bank know that it's the employee logging in, not a hacker? How is military communication encrypted? How do they control satellites?

If a quantum computer learns to break sha256, you'll have more things to worry about than bitcoin. Also, quantum computers are not owned by normal people. These are multi billion dollar installations run by groups of scientists. Even if they finally defeat the level of encryption that will allow them to take possession of a bitcoin address, doesn't mean they'll start stealing money from people. Most people want to do good, aim for the Nobel Prize, not to end up in jail for theft. When they publish they research and show it's possible, we'll have time to update the protocol.

You’re asking my opinion? Well, a quantum computer will be used for exactly that — breaking into banks, enemy comms, satellites. We’re already hacking each other just fine without quantum tech, by the way.

Think back: when humans discovered the nuclear chain reaction, the first thing they did was build a bomb and drop it on Japan. It’ll be no different with quantum computing. And of course they’ll crack enemy Bitcoin wallets too — how could they not?
