I have put a small amount on this website and received payouts. I have not tried withdrawing yet. I am worried because of a couple things. There is no proof of an actual mining operation. All payments and payouts are in BTC even though it's a scrypt mining operation. The owner is completely anonymous. Some people have claimed that the amount you receive from your kh/s don't match the amount you'd receive from a normal mining pool closely enough. Why use a .cc domain? However, this website looks more promising than any other scrypt cloud mining sites I've seen. Seems to be secure-minded. The admin/support post on the chat box a lot.
I want to end this post with one question. If the website is legitimate why wouldn't the owner want to prove legitimacy by posting proof of the mining operation?
