I think it has nothing to do with ETH, rather I think that ETC is completely related to the price of BTC, which is normal, the price of ETC had a great price reaching 176.72USD, given a huge uncertainty of the price. The market has been declining, after hearing the news from Elon Musk about BTC because the currency did not react, and has fallen by 43%:
The downward movement continued until May 13, when ETC bounced at the 0.618 Fib retracement support level, found at $83.4.
However, the bounce has been weak and technical indicators in the daily time-frame are bearish.
