I would actually still be very careful using electron cash. I saw one guy importing his private keys into electron cash and as soon the keys got imported the coins were send to addresses that weren't his. Electrum stated that the version isn't 100% stable yet so be cautious.
I would never import the private keys in Electron Cash while the Bitcoin are still in the same address, in this case I could only lose the Bitcoin Cash and nothing more, no?
Anyway my idea was to send immediately BCH to Kraken or some other exchange and delete that wallet, but the problem is how to get them...
