Most of the market has rallied and might be feeling the exhaustion and if you look at the market there were some coins that did not rally like the rest of the coins the market usually goes for a correction they would simply use them as a pumo and dump tool and hence the price might move up temporally.
I have not heard about specific projects using the ETC platform.
I have never heard of a project using etc dude lol, in my opinion etc is like a stable coin that moves like that. I bought this coin to find cheap fees between markets, lol
