Justin Sun said in an interview that advances in AI and quantum computing have made him more bearish on bitcoin. He argued that investors have not fully priced in those risks and that a network-wide Bitcoin upgrade within two years would be nearly impossible. Sun runs the competing Tron network, which the source says is implementing post-quantum standards.
Arthur Hayes argued that holders can address quantum risk by avoiding exposed addresses and using newer signatures. Glassnode estimates that more than $500 billion in bitcoin sits in addresses with visible public keys; coins held in wallets whose owners do not return cannot be moved as Hayes advises.
