The OP is probably talking about using the electroneum CLI wallet mining feature. The monero wallet has this built-in feature where you can start mining to your wallet address by typing a command. The problem is, this wallet feature does not allow you to specify pools (AFAIK, or at least with basic configuration skills) so basically you are solo mining the blockchain. This will take years and really appear like its not working. Better to get some dedicated GPUs.
He shouldn't be doing it that way then. He needs to be setting his wallet address in the config of the miner.
