This can trigger bad image of bitcoin investment by many people. So cloud mining is not a solution to earn income.
i paid 3000usd for my mining rig and electricity and all the other gubbins.
some people want to mine but don;t want the hassle of the kit etc. Cloud mining offers a way to mine actual coins, and remember GM allows you to use you hash rate against other coins on some contracts.
not everyone wants to trade maybe they just want a steady stream of coins on a daily basis. my mining rig will take 12 months for roi on best case.
People should be allowed to make up there minds with all information available, you wont get rich from it but it will generally return better than a bank i have found. i don't follow the crowds i like to diversify, so owning coins, mining them both cloud and physically covers all bases for me.
