I'm hoping that in the future you will be able to release another block of shares, but for sale using Solidcoins/Microcash. This is probably the only viable investment I'd be willing to trade for my SC.
Also, as a comparison, Vircurex went public on Cryptostocks back in early February. Shares were offered for .1 BTC and, at one point, I think they managed to skyrocket to about 1BTC each. Now, the value is a reasonable .25-30 BTC.
MCXNow is a smaller exchange but it is also much newer. Furthermore, when MCXNow was turned on, I was hooked from day-one and I've found the experience much more reliable the Vircurex.
If history is any indication of investment worth, a .1BTC/Share buy-in will almost certainly be a good investment, even if you want to sell all on on August 11.
