Howard Fischer was recently interviewed on yahoo! finance discussing how the global nature of Blockchain has made it problematic for U.S. crypto regulations.

"There are people who say let's not regulate it at all. Let it collapse. If it does, no real harm. I mean, the harm is to the crypto environment. But as long as the crypto collapse doesn't cause contagion to the traditional legacy financial structure, there are a lot of people who say let it live or die on its own merits or lack of them."
