If you have free money or unlimited wealth, then only try this stunt. As cloud mining sites are expert in luring people into investing in their hash powers. I still cannot believe that, people are falling for these scams repeatedly again and again. No one other than the cloud mining site’s owner will be profitable. Moreover yes its very hard nowadays to mine Bitcoins with CPU or GPU, yes some altcoins are still mineable, but yes these altcoins price varies, so it’s very risky again. So yes OP ask your friend to avoid these types of economical stunts.
