i will find a wallet where i can import the privkey, i looked both coins up on explorer and there the exact amount of coins shows up.
but for the portis wallet: sure i imported my pivkey and then purchased eth with banxa, but what if i had purchased eth and then etc in the wallet, i wonder would it add coin value to one and the same priv key?
Just leave Portis wallet and try to use another multicurrency wallet like Trust wallet. It supports importation of Ethereum and ETC classic blockchain private keys.
Not sure if I understand the second part of your question. Can you please rephrase it? What do you mean by "
would it add coin value to one and the same priv key?"
