I have read about many scams in cloud mining area and don't trust them. Anyway after cloud mining I won't have anything. If I get a unit in hands at least I will have some thing to sell, here you were right. I have found on ebay few sellers who offers knc titan cubes for about 1700-2200 usd in working order. I don't want to mess with coins, paypal is much more secure to deal with.
2200$ will not be profitable.. thats about 10 months ROI. here is the calc -
