I think the point is.
Considering all the costs, hardware, electricity, cooling, personal time, knowledge.
A mining contract is more expensive than mining hardware?
If mining is or not profitable is another discussion.
At least is my point of view.

For me, the benefits of using a mining service like ours
www.byteminr.com is in the ease of use, the ease of scalability and, as we grow, the benefits of economies of scale become more apparent.
The simplest analogy is that you can buy your own web server hardware for your business, run it, service it and host it, or you can buy a cloud hosted package from Amazon, Rackspace or whoever. For most people, having your own websever is just not worth the hassle, I believe the future of bitcoin mining will be the same.
