Very honestly, it looks like a great coin. If it works, and I believe it does, then it should be very successful.
But could one of the developers clarify any connection it might have with dubaicoin? The similarities defy chance and it would be better to clarify if there was some connection between the two coins.
I strongly support geo, own a fair amount, and hope it does well if it is a decent coin. The dubaicoin overlap is either clarifiable or it is something that needs to be covered up?
Looking at the post above the only similarities I see between GEO and Dubaicoin is blocks numbered 2-100 for (instamine protection). All the other coin settings seem to differ in terms of mining algorithm, numbers of blocks, block reward and even the decrease in block reward over time.
If you look back, GEO was originally planned to be an X11 algorithm based coin, but after some constructive feedback from the community it was decided to switch to the Qubit mining algorithm. Since launch the GeoCoin project has developed and delivered the Google Maps GeoCashing interface and we are very close to launching the new and improved MapBox interface shortly.
Hope that helps clear some things up!
