I too am very optimistic.  I think YACoin's crazy path so far is its greatest strength.  The concept behind most of the other alt coins has been to reproduce the opportunity to get-rich-quick as many of the early investors of bitcoin have enjoyed.  The problem is that that greedy mentality actually results in the opposite happening.  I believe once you see the NFactor change and GPU mining becomes futile, the price will skyrocket back.  I think the NUMBER of people with some amount of YACoin right now is large even compared to alts with a much greater marketcap at this point.
