This isn't really true.  With GAW's Zencloud you can sell your mining power back at anytime.   That means you don't have to make nearly as much to get to a positive ROI.   At Hashie all you can do is buy or hold.  I'm not even sure Hashie will ever be profitable, it will depend on the bitcoin difficultly.   Best case is over 4 months to get your initial investment back.   

If you want to compare you should compare against pbmining or places like that where you can't easily sell your holdings.
