Bitcoin Fortress: El Salvador Shields $678-M From Quantum Threat

El Salvador moved its national Bitcoin stash into multiple wallets on Friday as a hedge against a future cryptographic threat according to official posts and blockchain ￰0￱ country transferred 6,274 BTC — roughly $678 million at current prices — out of a single address and into 14 separate addresses with each new address holding up to 500 ￰1￱ Wallets To Limit Exposure Based on reports from the Bitcoin Office the move was meant to reduce the impact of any future quantum ￰2￱ said the shift was a simple
