Provided that the team will continue working just as hard, I don't think there's anything stopping ZED from becoming a top-10 currency during the course of the next year or so, I'm really excited about the prospects here.
Yes, indeed the team must work harder, I also think that in the future zed will be the top 10 in the world of cryptocurrency 
Looking at the Stellar it takes some years to become the top 10 on CMC. But here we`ll have finished platform with the real usage before the ICO ends, so who knows)
But I`d rather suggest to take a closer look at the platform benefits and ZED features than make those predictions.
