Well, im now use Genesis and hashflare. Well, im on profit but isnt really big profit. But atleast i got some profit. And i dont recomend it for now. Because when i use cloud mining, my profit is about 20%-50% per year. I want try trading because of that. Better not investing on cloud mining. Or maybe you can buy your own mining hardware, thats good too maybe.
Make sense, why people want to rent their mining if it could bring more benefits without share? I would agree if you invest on big project which they just started to build a mining farm, so that they collect money from investors. But, in the end if you have big capital, better to build it by yourself or with your own team. However, you need at least $2000-$3000 minimum, depends on your country.
