In next months Ethereum will convert to POS
So that are miners will switch to mine Etc?
and if that happens how much do u see Etc in near future?
This is not true, PoS won't come to ethereum until the end of next year. Where did you read that they will be moving to proof of stake in the following months??
About your question, mine ETH, it's worth more and ETC is like BitcoinCash, a fork that no one uses.
