Wall of text incoming, I'll break it down into sections with headers.
The part that seems to really trip people up about GHX is that you're buying a portion of a farm, not a miner. So if I have 1000 GHX, I have 10 TH of power on that farm. Right now, that's S5 power, but the goal is to find ways to incrementally upgrade the farm so that in the future hashpower will be S7, Avalon 6, maybe even SP50 (industrial-grade) hashing power.
Now, the economics of this are certainly difficult. It requires a buy-in from investors (all of us) in the sense that 10 GH of power can certainly be bought more cheaply from other places. However, none of those places are attempting at all to upgrade that 10 GH to cope with obsolescence. GetHashing is the only verifiable operation I have found that at least attempts to do this.
It requires a hell of a lot of work, so there's definitely risk associated, but if we succeed, we have a sustainable farm that upgrades over time. That's something that no-one else is even trying for in terms of crowd or cloud-mining. That's part of the reason that GHX has a far more stable re-sale value than most mining investments. The upgrading is untested waters, certainly, but if we pull it off, it's going to be awesome.
One of my favorite things about GetHashing from a nerd perspective is the technology they put together. We have a trust-less "cloud" platform with a built-in wallet where you still maintain 100% control over your privkeys (they are stored locally on your machine, not the gethashing servers). We have a pretty damn awesome color aware portfolio with some nice built-in tracking for revenue assets. We have a trust-less exchange that allows people to buy and sell assets while maintaining control of their btc and their assets right up until the simultaneous swap.
Are all of those components extremely user-friendly? Nope, but some of that can be improved over time as resources become available (time and money). The point is, this stuff is hellishly difficult to actually do, and very few people have even working proof of concepts for this type of tech. Some of the user experience can be improved, some can never be improved without sacrificing the security, but either way this tech should not be shrugged off as "eh, does nothing for me". It's all very useful building blocks for future ideas or innovations. Also, some of it actually makes us money as well. Ergo, my third and final point:
Gethashing also does something really nice that most people know about, but don't realize the reasoning behind. They self-fund investments and freely give away money that the "company" earns. GHMinting adds to the payouts rather frequently via GHCoinex. GHMinting is a pot of Proof of Stake coins which is entirely funded off donations and gethashing revenues, and has produced 5.25 BTC that was included in payouts. The GHXchange fees also give a cut back to all holders of GHX each week through "GHRebate". In other words, GHX payouts include small elements that are given by gethashing. These elements do not currently (and most likely would never) make up the majority of payouts, but it again shows that gethashing is about benefiting the holders of GHX, not the company itself.
If you're like me at all, you also hope that one day we will be successful enough to run GHPool and attract external miners. If that occurs, I have no crystal ball, but I'd expect there will be at least a passive benefit to GHX owners.
So, in conclusion, think of it this way. Anytime you're buying 10GH (GHX) from gethashing for "more than market price", you're investing in the entire process. That process is how we achieve sustainability, and you're seeing returns from that investment every time you get a payout from GHCoinex, every time you get a payout that includes GHRebate (every Sunday), and every time gethashing is able to purchase new, more efficient hardware.
I don't see gethashing as cloud-mining where I'm trying to make my money before mining becomes unprofitable. I see gethashing as "crowd-mining" where we're all trying to build a large mining farm, and make money in the process. The larger we grow, the more opportunity we have, the more we can do, and with what these guys have accomplished already, that's extremely exciting to me.
