Nic Carter, a partner at Castle Island Ventures, addressed why Satoshi Nakamoto did not fix early Bitcoin's quantum vulnerability during a Delphi Digital podcast on January 10, 2026. Despite acknowledging the quantum threat, Satoshi left a vulnerability affecting 1 to 2 million early Bitcoins. Carter suggests this was because Bitcoin's value was negligible in 2010, and the code was easily modifiable. Satoshi likely believed that any breach could be swiftly addressed with an upgrade, not foreseeing the massive value and complexity of system upgrades today.
