My Final question is: Are cloud mining websites worth it? Can you earn much from them? Are there any vouched for/trusted cloud mining sites?
No. If they could earn through mining they would do it alone. They want earn more through you loosing by "investing" with them.
I second this completely. The cloud mining sites that are out there are not worth it in any way. Their numbers never ad up and when they start to loose money, they are uping their fees and you will have nothing. So stay away from cloud mining.
