Nate Geraci, president of ETFStore, has raised concerns about the potential threat quantum computing poses to Bitcoin. Geraci emphasized that no system is entirely secure, suggesting that Bitcoin, as a human-made technology, could be vulnerable to future advancements in quantum computing. This perspective contrasts with views from figures like Samson Mow and Graham Cook, who maintain that Bitcoin remains secure for now. The discussion around Bitcoin's security in the face of quantum computing is anticipated to intensify as 2028 approaches.
