Cardano founder Charles Hoskinson stated that BIP-361, proposed for Bitcoin's quantum computing risk, is mistakenly called a soft fork; in reality, it would require a hard fork to implement, which conflicts with Bitcoin's long-standing development culture of opposing hard forks; he believes the scheme relies on a zero-knowledge recovery mechanism based on BIP-39 mnemonic words, which cannot cover approximately 1.7 million early Bitcoins (including about 1 million believed to belong to Satoshi Nakamoto), as these assets were created before 2013 and lack corresponding mnemonic structures; if executed according to the current plan, these assets could be permanently frozen.
