Bitcoin is currently facing two major issues. First issue: Around 1–1.1 million coins related to Satoshi Nakamoto are mostly stored in early P2PK addresses, where the public keys were exposed on-chain from the very beginning. If a sufficiently powerful quantum computer emerges, theoretically, Shor's algorithm could be used to derive the private keys from the public keys. The total BTC with exposed public keys is approximately 6.4–7.1 million coins (about 30–35% of the supply), including reused addresses, Taproot, etc. If breached, Bitcoin could crash 99% in a short period. Second issue: Can we propose to freeze these dormant coins? Theoretically, it's possible. But it goes against the core principles of blockchain: "unfreezable, unseizable, private key supremacy." This would likely destroy Bitcoin as well. With the advent of the AI era, the pace of quantum computing breakthroughs has exceeded expectations. Various models suggest breakthroughs could happen by 2028 or earlier. These two issues are already the most urgent challenges facing the Bitcoin community and even the entire crypto space.
