There’s a lot of hype—and FUD—around quantum computing “breaking Bitcoin,” but the reality is far less dramatic. Quantum computers powerful enough to crack Bitcoin’s cryptography don’t exist yet, and experts agree they’re still many years, if not decades, away.
More importantly, Bitcoin is people's network. Banks, governments, military communications, and the entire internet. If quantum computing ever reaches that level. But Bitcoin has no single point of failure.

Quantium computing represents unique risk to bitcoin. Other systems can be updated centrally and quickly, or can be temporary stopped. Bitcoin cannot. Furthermore an updates to bitcoin are very slow to be introduced. And after an update that introduces quantum resistant addresses, people need a lot of time to move all their coins to the new addresses due to limited block space
Not all "experts" agree that we are decades away. And keep in mind that "experts" often underestimate how fast some of the technolulogy is developed. And furthermore even a 5% risk warrants action. We don't have to be 100% certain.
Bitcoin needs to start work on quantum resistant addresses now. This is the point, not abandoning bitcoin.
The practical distinction I like is: quantum risk is real enough to keep protocol people thinking, but not urgent enough for users to panic-move coins or trust whoever sells a miracle fix. The near-term user habit that already helps is address hygiene: avoid reusing addresses, understand when a public key is exposed, and follow consensus-level migration work if the threat ever becomes concrete.
