I smell that this is one of the big nails, which will close digital's currencies coffin (i.e. "raised eyebrows", regulations etc.).
What are the regulators going to do? They can't stop drugs being bought sold. How would they stop these ICO? Stamp their feet?
Probably, but they could at least make it illegal for the residents of their country to participate in ICOs and crowdsales, if this happens, then that is going to stop a number of people not everyone but some, especially those that do not know any better and follow orders, for the rest they will keep doing business as usual but the rewards are going to be smaller.
