Coinbase, which holds 5% of all bitcoin, wants the quantum fix started now

Coinbase, which holds about 5% of all bitcoin, is urging the Bitcoin community to begin preparing for quantum computing threats now. The exchange proposes flexible addresses, a backup quantum-proof key, and a separate discussion about lost coins. While this is a forward-looking security concern rather than an immediate price catalyst, traders may monitor how the debate evolves given Coinbase's large BTC holdings.
