I actually have a 4 month old contract with hashflare. I will admit that I am profiting due to the price of bitcoin. Trouble though is I am earning a lot less than the first day I signed up. I think this has a lot to do with rising mining difficult. I remember on the first day I signed up I was projected to earn 0.05 bitcoin a year. Now it is barely above 0.03 in a year. I am hoping before my contract ends that hashflare will lower its withdrawl fees. At current pace I will have difficulty withdrawing my earnings unless I invest more. I may do that just for the sake of getting my bitcoin in the end.
Just saying not every mining contract is a bargain deal. I would avoid hashflare unless someone can really put a lot of money into it. Some where around $1,000 or more.
