Bitcoin analyst James Check has raised concerns about the potential impact of quantum computing on Bitcoin's security. According to NS3.AI, Check highlighted that approximately 1.7 million BTC, valued at around $145 billion at current prices, could be at risk if a sufficiently powerful quantum computer were to break Bitcoin's cryptographic signatures. He suggested that while Bitcoin's normal turnover could gradually absorb this supply over several months, the governance surrounding vulnerable Satoshi-era coins presents a more significant challenge.
