But they're not actually enforcing existing legislation, per se. One of the major issues wrt crypto in the US is that the SEC won't tell you what's legal or not. Seriously, when companies ask them "is doing XYZ ok?" or "can we trade ABC?" or "what can we do to be in compliance?" the literally SEC refuses to issue clear guidance. To say many industry players are upset is an understatement.
