According to reports, a new round of debate over quantum computers and Bitcoin has pushed technical questions into market talk.
Some investors say the threat is close enough to affect price. Charles Edwards, founder of Capriole, warned that Bitcoin could fall below $50,000 by 2028 if the network is not made quantum-ready.
Developers Urge Caution
Jameson Lopp, a Bitcoin Core developer and co-founder of custody firm Casa, has argued that migration to post-quantum cryptography will not be quick.
Lopp told followers on X that while quantum machines are not an immediate danger, moving the protocol and users’ funds to new signature schemes could “easily take five to 10 years.”
He agreed with Adam Back, CEO of Blockstream, who has also said the threat is not near-term but should be watched.
No, quantum computers won’t break Bitcoin in the near future. We’ll keep observing their evolution.
Yet, making thoughtful changes to the protocol (and an unprecedented migration of funds) could easily take 5 to 10 years.
We should hope for the best, but prepare for the worst.

Community Split Over Timing
Reports have disclosed a widening gap in how the community views the timeline. Some venture capitalists and investment firms say quantum risk is imminent and should be priced now.
On the other side, long-time Bitcoin advocates question the urgency. Pierre Rochard argued that quantum-resistant fixes can be paid for by non-profits or VC funding, and he suggested an attack would be so costly it would require government-level support.
Samson Mow, CEO of JAN3, pushed back with a plainspoken line about current machines, saying they “can’t factor the number 21 — not 21 million — 21,” to make a point about how far current quantum hardware still is from breaking Bitcoin’s cryptography. Andreas M. Antonopoulos has also weighed in, noting that upgrades are possible ahead of any real threat.
What Upgrading Bitcoin Means
Changing Bitcoin’s cryptography is not the same as updating ordinary software. According to developers, the distributed nature of the network, the variety of wallet software in use, and the many holders who do not actively manage keys make a broad migration difficult.
BIP 360, a proposal that would add a quantum-ready signature method for BTC, has been pushed by some figures. Charles Edwards has called for node operators to enforce BIP 360 to speed adoption, while others say enforcement and coordination would be tricky and could take years.
Calls For Protocol Change
Market watchers should note the difference between theory and proof. The technical camp says there is time to plan and roll out changes carefully. The investment camp warns that market confidence could wobble if measures are not taken quickly.
Calls for action include funding research, testing signature replacements, and building migration tools that exchanges and wallets can use. The debate has become public because price concerns make the matter of practical interest, not just academic.
