With the new Ethereum fork - Do we need to do anything with our ETH which is on a cold wallet
there are several hardforks that will occur this month. if you want to get ETCV coins you have to put eth in a personal wallet like MEW or imtoken. but this is not an official hardfork by the ethereum team.
the only hardfork that the ethereum team will do is Constantinople's hardfork. in this fork will not produce new coins.
