• —At least 2.6 million BTC are at risk, including about 1.7 million in old P2PK outputs
• —ECDSA and Schnorr signatures are vulnerable to a sufficiently powerful quantum computer
• —BIP-361: first quantum-resistant addresses, then a ban on spending from vulnerable ones
• —Opponents of a freeze see it as a restriction of property rights
