99% of the cloud mining website are scams based on HYIP or ponzi schemes! Even if you find cloud mining which is not scam(and 99.99% of them are scam), you will hardly earn money unless you have lots of referrals, and in that case your referrals will hardly earn money.
Ask yourself - if you would have mining equipment, would you rent it to someone and pay interest for next 1-2 or i don't know how many years? I don't think so.
