EDIT: I have posted a more in depth response on the cryptocurrencytalk thread found here

I see this as a perfect splash page for an app -- the first and last image. I also like the middle image but I think the text could be integrated more.

I do not think the logo of the first and third images will scale well for exchanges.

I like the idea of having this image as a complex logo -- something for shirts, apps, for places where it fits -- and the proposed simplified logo for exchanges and wherever else a more simplified logo is required.
