The top 3 seems to have a huge potencial.

But you should also consider that the late adding of DGC EAC and DGB to the poll had drastically decreased their chances against other coins (Wordcoin mainly) that have been added right from the start.
For instance, as you can see, EAC used to have a much better score.
