Coinbase Maps Bitcoin’s Quantum Risks While Safeguarding 5% of BTC

Coinbase, which says it safeguards roughly 5% of all bitcoin, published an analysis of the technical and operational hurdles bitcoin must clear before quantum-resistant security becomes practical. The exchange argues that simply swapping in a new signature algorithm will not be sufficient, framing quantum migration as a broader test for the network. The piece is an explainer on a long-horizon risk rather than a near-term catalyst, so it is unlikely to move BTC prices on its own.
