I need to say that I'm a long-term holder of OMG (I don't trade, I simply hold it) and I believe that this is one of the hottest projects out there, especially because it focuses on a region that has a worrying percentage of unbanked population: Southeast Asia.
Even though countries like Thailand have a minor percentage and good credit card/cash card options like http://www.umayplus.com/cashcard, there is still a market for OMG, because if they can successfully reach this segment of population, then the valuation of the token will reach completely new levels.
All in all the end goal of OMG is to bank the unbanked by using Ethereum-based technology for peer-2-peer transactions, and as the end is serious and truly professional, I can only say that it is one of the best long-term holds in the market. If they reach the unbanked popultation not only of Southeast Asia but of the world, then we can only expect it to grow massively in value.
