Who are the best crypto skeptics?
Who are the most prominent and influential skeptics of cryptocurrency? Are there any economists, financial experts, or other professionals who have raised concerns about the stability, security, or potential risks associated with investing in digital currencies? I'm interested in learning about their arguments and viewpoints, as well as any evidence or research they may have presented to support their skepticism. Additionally, I'm curious about whether there are any notable skeptics who have since changed their minds or become more open to the idea of cryptocurrency.
