Doesn't yet look like a greenlight per se, but rather the first official flag of caution post-launch. "This statement is my own and does not reflect the views of any other Commissioner or the Commission. This statement is not, and should not be taken as, a definitive discussion of applicable law, all the relevant risks with respect to these products, or a statement of my position on any particular product. Additionally, this statement is not a comment on any particular submission, in the form of a proposed rule change or otherwise, pending before the Commission." As I read it, the whole letter seems to say that they reserve the right to intervene at any time if they deem a particular cypto stepping on their regulatory toes. Some fine lines being drawn, etc.
