((Oh dear lord... I may not be any sort of economic genius, but I do know that at the percentages he's selling at, and for such low prices, he either has some REALLY low faith in the business venture, and/or he has no idea how investments work at all. For example, if the business is to actually remain "yours", you would never sell more than 49% of the stock in it, and even then only in an extremely desperate situation. Always hold 51% under your own name to remain majority shareholder. Also, I imagine that the space stock exchange is just like the New York stock exchange but on a larger scale, so this wouldn't be stock in the sense of stock market, being an unlisted startup, but rather just stock in the business itself.))
