Does quantum computing threaten cryptocurrencies? Or is it just a temporary scare?

Question

【BitPush】Will quantum computing ruin the cryptocurrency industry? This topic pops up every now and then, causing panic. Recently, a leading asset management firm released a “Digital Asset Outlook 2026,” pouring cold water on this issue—simply put, the quantum threat is real, but in 2026, there’s no need to overthink it.

Their assessment is this: although quantum computing can theoretically break Bitcoin’s cryptographic systems, based on current progress, the first capable quantum system is unlikely to appear before around 2030. In other words, there is at least a few years of buffer time.

This doesn’t mean the industry is sleeping. Research on post-quantum cryptography has been ongoing, and major projects and institutions are preparing for this long-term challenge. However, in the short term, this threat is not strong enough to impact the valuation system of cryptocurrencies. Instead of being anxious, it’s better to focus on the real changes in the current market.

It's the same old story again, each time it can scare a wave of sell-offs, hilarious.

A few more years to go, let's understand what's happening right now first.

We have to wait until 2030, so what am I worried about now? Let's first understand the current market situation.

It's the same story about quantum computing, heard it every year, still as frightening as ever.

Why rush about 2030 now? Maybe the technological roadmap will change again.

Here we go again with the old routine of hype about quantum threats. It's really annoying; 2030 is still a long way off.

Here we go again, rehashing old news. Worrying about 2030 now is a common problem among crypto people.

It's the same rhetoric about quantum computing destroying the crypto world, I'm already tired of hearing this explanation.

20230? Then what should I be worried about now? It's better to focus on whether we can make a breakthrough tomorrow.

It's the same old story about quantum computing causing the end of the world. This joke has been told for years.

Every time it says next year will be the year, but what happens? Still facing constant delays.

Rather than worrying about it every day, it's better to focus on the rise and fall of coin prices—that's the real indicator.

Anyway, by 2030, I’ve already been hardened by the market's lessons.

By then, whether post-quantum cryptography exists or not will be irrelevant, haha.
