Muneeb Ali says Bitcoin has about two years to start its post-quantum upgrade

The Stacks co-founder used his Token2049 keynote to lay out a four-year window for upgrading Bitcoin and moving coins before quantum risks grow Bitcoin has a deadline problem, and Muneeb Ali wants everyone to start counting. Speaking at Token2049 Singapore on October 8, 2026, the Stacks co-founder said Bitcoin has roughly two years to upgrade, then about two more years to move coins before quantum computing risks intensify. Phase one is the upgrade itself: getting quantum-resistant signatures into Bitcoin. He put that window at approximately two years. Phase two is migration.
