BIP-361 Proposal Risks Freezing Satoshi's $80B Bitcoin at $76,547 Amid Quantum Fears

Bitcoin faces heightened downside risk from BIP-361, a developer proposal filed April 14 requiring holders to migrate to quantum-resistant addresses within five years or permanently freeze coins—including Satoshi's estimated 1.1 million BTC worth ~$80 billion. The plan responds to a March 31 Google Quantum AI paper indicating quantum attacks are more feasible with less advanced hardware. While consensus is slow (full migration could take ~7 years) and less intrusive solutions are emerging, markets remain wary of any erosion in holder control, pressuring prices near $76,547 with a $1.5T market cap. Investors eye developer debates for Bitcoin's long-term risk profile.
