Will you please clarify some things:
Shares:
Are we buying shares of SWMC the company, or shares of this one SWMC website's profits? If it is for all of SWMC, can shares be resold? Any plans to use something like Havelock investments or Cryptostocks? And how are shareholders represented within the organization (for example do we get to elect a board member or get a vote on decisions such as fee price)?
It depends on what precisely you are referring to. If you are referring to the post immediately preceding your own (which is my assumption), then as a financial contributor to SWMC's Hashing Exchange development, you receive a portion of 25% of the total trading fees as outlined above. All costs are paid out of the remanding 75% of trading fees. This is true only for the SWMC Hashing Exchange as that is the offer specified. That's pure profit on the contributors side of this offer, so the ROI estimation is accurate if you assume the values given in the example as being accurate. To be clear, those figures are indeed accurate, but only if the full trading volume as represented is achieved. As with any investment, there are risks involved, so whether or not those numbers are achieved or not can't be known. If you're wondering where the company will make its profits with the Hashing Exchange, it will be in the sale of Hosted Wasp miningware, Bitcoin mining and hashes from SWMC's own miningware sold on the exchange. But this is just one facet of SWMC's business model, there are lots of opportunities to be explored in the future of Bitcoin's economic expansion. Most of these opportunities haven't even been invented yet!
As far as shares in the company itself are concerned, you would be talking about a Founders Contract which does offer 25% (this would be after cost) of company profits as a perk. The back end process of the Hashing Exchange will also handle the sale of company shares and contracts, which will also be tradable, but this function will be a different part of the main website. I plan to expand the trading choices in the future to take advantage of the various decentralized exchanges like counterpartyd or Bitshares PTS (I will never use Havelock!) Investments are made and have rights to profits based on the type of investment made. There will not be board members because that would require a different business model than that which I wish to use. (I just simply wouldn't function well in that type of political environment.) Even so, I would never ignore those who are supporting SWMC and will always seek to make them happy and be worthy of their trust. Voting on specific actions will be offered based on need and customer opinions and if it seems the best way to resolve a serious issue.
Competition:
What is the timeline for the completion of the website? Who is developing and maintaining the website? CEX has HUGE volume, in order to earn 4000 BTC in revenue a day, they trade ~310,000 in gh/s per day (4000 BTC volume/ 0.01290146 current price per gh/s). This doesn't even include gh/s that wasn't traded and just kept mining. How do you plan to get even a fraction of that kind of volume when CEX has a huge lead and millions in the bank? With its bigger bank can't CEX buy gh/s in greater bulk, thus paying less per gh/s and beating your prices? How do you plan to combat this especially since CEX can just buy WASPs too if they are cheaper per gh/s?
If you look around at other industries, you'll notice that, for the most part, there are at least three companies at the top of the industry, these are often referred to as "The Big Three." So far, there is only one company of note that trades mining hashes like a commodity and that is CEX. One issue with CEX is that you have to use your mining hashes on their mining pool. Not so long ago, CEX's network hashing share was threatening to surpass more than 50% of the entire Bitcoin Hashing Network, this resulted in fears of the dreaded 51% attack becoming possible and a loss of a significant of support for CEX.
One of the ways that SWMC would use to avoid such concerns is to allow those who exchange hashing power on SWMC's Hasing Exchange to choose their own mining pool or even mine solo if they wish. Combine that with hosted mining that offers the same benefit, then I believe that The SWMC Hashing Exchange's model will have a great deal of support within the Bitcoin community and that will lead to a successful business model.
Additionally, as time marches on, the costs of Bitcoin mining will rise beyond the ability of most individuals to afford (to keep up with) on their own. Just as mining pools helped solve this issue before, collective participation in mining farms will be a similar solution moving forward. Hashing exchange platforms and similar solutions will become the norm, so the market will only increase as things progress in this direction. It's advantageous for SWMC to establish itself while this trend is still in its early stages. It is also advantageous for investors to take advantage of any offer that gives them a significant portion of the income generated by trading fees. It may not be so much now, but the potential is significant as time and the associated market share progresses. In the future, a volume of 4000 BTCs worth of trading in a day will seem rather small for a single exchange.
The concern of the Bitcoin community over keeping the Decentralized Nature of Bitcoins Decentralized Network sanctimonious will limit CEX's ability to grow, but does allow other organizations to flourish if they offer a way to profit/participate in Bitcoin mining and help preserve Bitcoins Decentralized Network at the same time. CEX's enormous coffers do not compare to the total funds available amongst the Bitcoin community as a whole. So if SWMC gains significant support in the community funding shouldn't (won't) be an issue. Besides this fact, it isn't SWMC goal to surpass CEX or beat them in any race for hashing power. As a faithful believer in what Bitcoin can provide to the world, my goal is to support the Bitcoin community and the Bitcoin Network as best as I can.
I believe CEX already uses their own hardware design using bitfury chips. So if they switch to Wasps, I don't see that changing much at all. On top of this, CEX doesn't market their hardware and all of the hashing power that they sell is on their exchange. Again, I don't see that changing much even if they adopt the Wasp designs. Add to this what I just mentioned above and I have even less concern about this issue.
Costs:
Finally what about costs? Running a website at the scale of CEX costs thousands of dollars per month in server costs alone. On top of that it requires not just a developer but also things like a support team and a ton of add on services like Mandrill/Mailchimp, Cloudflare and Zendesk (these alone are like $500 per month for a high traffic site). And that is just the website, it doesn't include maintaining thousands of Asics and paying for electricity for them.
Well, CEX didn't just materialize into existence one evening all ready to go, they had to grow over time. As SWMC needs to expand its capabilities, it will do so. The rest of what you mention is just the costs of doing business and when the time comes for those things to be added, well, I need not repeat my statment.
In your post you have taken the revenue earned and divided it between shares without subtracting any costs whatsoever. This does not calculate ROI per share it calculates net revenue per share. Costs take up the vast majority of a business' revenue thus your ROI calculations are completely wrong.
I believe I already addressed this point.
