For the first one, I think it should be something like 100 Starz=1 Ecoin. 1,000 Starz becoming one Ecoin would make Fantagians too poor. But it's a very good idea.
For the second one, they already had something like that. In the fall, Fantage had a Youtube video contest, and the top ten winners all got 10,000 Ecoins each.
