https://www.coindesk.com/ethereum-classic-is-down-30-since-its-listing-on-coinbase/Remember that when ETC got fully listed on coinbase there was was probably a lot of ETC that was release to people AND coinbase from the DAO fork. All of this could be making up a percentage of the recent dump on the market. It really shouldn't have any affect on the long term price of ETC.
It's important to realize that ETC has a place on many crypto currency hedge funds, this will reflect a much higher long term price target for ETC as the overall crypto market matures.
Buy a little bit here and there to make up a small percentage of your overall portfolio and wait.
Would recommend the same for Zcash, if you don't believe me then go back in this thread to my post, I was one of the only people posting on here saying ETC will get listed next on coinbase before the fact....when everyone and their mom was saying it was going to be ripple.
ETC is NOT on coinbase yet it's on Gdax or coinbase pro, the Casual Investor has no access yet. The Pump (if it comes) will be when there's an ETC wallet and buy/ sell on the Dashboard of the Coin base app.
