You can rent hashing power on NiceHash and point it to Nanopool to mine Ethereum Classic. To create an order on NiceHash you have to use the following settings:
Algorithm: DaggerHashimoto Stratum hostname or IP: etc-eu1.nanopool.org (or any other Nanopool's server) Port: 10100 Username: YOUR_WALLET.YOUR_WORKER/YOUR_EMAIL (example: 0x9eab4b0fc468a7f5d46228bf5a76cb52370d068d.NHfirstname.lastname@example.org) Password: x
Please keep in mind that you have to use an Ethereum Classic address when creating an order on NiceHash, otherwise, you will not receive your reward.
NOTE: By filling your email address in, you will be able to receive email alerts from the pool each time your miner goes offline, otherwise, fill a passphrase instead to access the account settings.
