Which crypto coin is the most useful and profitable coin in year 2014?

I have just read about EDUcoin on https://bitcointalk.org/index.php?topic=486600.0 . It will be used for:
MOOC (Online courses)
College tuition
College loans
Crowdfunding, Tipping
Foreign exchange studies
Daily student expenses
Pizza, Pizza, Pizza...
Do you think it's good and long live?
Am I wrong if I think EDUcoin is the most useful and profitable coin in this year 2014?
