Sorry mate Electroneum have stopped their mining in 2019, their cloud mining through mobile phone is no more active too, the only way to earn free Electroneum ETN right now is through a program called Electroneum Reward, it's available in their app dashboard, I think you will have to complete some task to get free ETN
thanks for your reply.. is there any coin profitible (except monero?) to mine on cpu?
I don't think so, RandomX Algorithm (Monero) is the only CPU friendly algorithm that I know off, there used to be a good one called Yenten coin that's minable on CPUs but I've lost track of the project and no one is talking about the project anymore, I doubt there is further development on the project
