How quantum computers could impact Bitcoin supply


Researchers estimate quantum attacks would affect different parts of the Bitcoin supply differently:
🐷 65.4% (~13M BTC) — safe under current address structures
🐷 25% (~5M BTC) — potentially vulnerable due to address reuse, but can likely be moved to safer addresses
🐷 1% (~200K BTC) — vulnerable by address type, but still movable
🐷 8.6% (~1.7M BTC) — vulnerable and likely lost, mostly early P2PK addresses
Bottom line: Even if quantum computing advances, most BTC is already safe or can be migrated. The main risk lies in very old or lost coins. ⚡
