I am a little surprised that US availability came before the App did. Judging by the language in the PR.. I am suspicious that there might be a problematic bug in the app. That the US has given the green light on ETX's so quickly is a huge signal. The Crypto/digital asset world is about to absolutely explode in my opinion. I am not sure how it will play out and what forms it shall take... but I expect the world economic landscape to change much like it did in the 1950's.... after the post war boom.
