Pretty good guide. Thanks for your work, I will check all reviews, ‘coz I’m strongly interested in potential of cloud mining. Compared with this article - http://miningtop10.com/ - your list is wider, but it’s still something I’d like to ask. What can you say about Bit Miner? It’s the only site which isn’t featured in your guide but it is in my example. It’s interesting to read your opinion.
