ETC is undervalued . we've seen in the past a lot of shitcoins making 10x its value in less than a week , so the answer is yes : ETC can cross 100$ in few weeks
I'll mark your words and lets see what will happened later.
Considering the market cap , supply and volume i don't think etc can do that in the near future.
Ethereum far more established , stronger support and a lot of people interested in it rather than in eth.
