Carrion,
We like the colors, but we could use 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 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.
We think we can get it with you !
Best Regards!
