Nic Carter: Why Satoshi Did Not Fix the Quantum Vulnerability in Early Bitcoin On January 10, 2026, Castle Island Ventures partner Nic Carter @nic_carter discussed this issue on the Delphi Digital podcast. Satoshi explicitly mentioned the quantum threat but left a vulnerability affecting 1 million to 2 million early Bitcoin. Carter believes this is because, in 2010, Bitcoin's value was basically zero and its code was easily modified. Satoshi assumed the system could simply be upgraded if broken, failing to foresee today's massive financial stakes and upgrade difficulties.
