We like the use more colors, like the other guy Max did.
Maybe we can try other combination, with brighter colours, like, orange, yellow, .. We're free to help us!!
Other thing that we could experiment is sutil icons as $, or conection, or "collect money", or this signal of mobile. We didn't find the time with the icons in any logo that people created, but we'll get there!!
Mobo is a website that users will download credits in "reais" (brazilian coin, like dollars) to go shopping in real stores and places, just to remind you.
