ETC has the battle to face that it is useless, and will continue to be useless. As the founding developers of eth has stated openly that they will focus on eth and NOT etc, the best etc can do is ride on the coattails of eth by copying developmental advancements directly from the eth code. And, as most developers have stated they will support eth and NOT etc, the effort is null.

ETC will fail, 100% at somepoint. There is literally no use that will ever put it into practice. ETH still has hope, but is way overvalued in the sense that right now it is worth a lot for being completely useless.
