Don't mine! You will never earn with mining. You will spent money to buy hardware to mine yourself and you will spend electricity. All the cost will never cover the earnings. It's the same with the cloud mining. You will buy power and the site which offer cloud mining will not scam you even here you will not earn because the difficulty will go high (probably not and probably yes but mostly yes) and you will have your invested money after 8 months or 1 year. And the earnings (if there will be) will very very low.
