I'm personally in the former (unregulated) category. The furthest regulation should go is KYC, and even that may be a bit too much (although I realize why .gov would force that). Does it suck that people lost a lot of money? Yes. Do I think the government should investigate this? No, because the flip side of having the government investigate this is government regulations, and I'd like to keep the crypto space as regulation free as possible even if it results in episodes like this.
