With many of the shares being closed-end in design it is indeed difficult to expand the base shares much further. That being said, I'd imagine if there was enough interest I may open up closed-end shares again for a period of time.

Indeed it is very hard to place trust in someone and I do my best to make sure everything is transparent as possible. I do a lot of work on my exchange (located here) to make sure that people know where money is going out and in and the present value of their shares. But as I state in all of my disclosures, there are risks inherent to investing and trusting in my not to scam people is inherently one of them. That being said, I'd imagine all of the people currently making money are glad they've made that leap thus far.
