ECCoin has the backing of a community which wants to make real environmental change. Sure, just like any coin you've got a large percentage of users who are only in it to try and turn a profit, but we also have people who want to set up environmentally friendly projects in which ECCoin plays a central role, and that's what separates ECC from most other PoS coins.
Will you please provide some examples of those projects? That would be something to promote, but it would need to be specific projects that are making good progress. Otherwise people will just say, "BS!" The only thing I know of is just a link to donate coins that's mentioned in the OP.
