Do I need to change all my coins to ETH or hold the coins until their price go up? What will be the best option for now?
I think you should keep it in your wallet first, because who knows there will be one of your coins that have a better price than ETH. So you can have more choices if you have more coins. does have ETH coins is better but we can not have other options, can only wait for one coin only that is coin ETH
