There are a number of things I think they can do to become more solid. Get out of the card business. Put penalties on owners that are geographically disadvantaged. Do not sell 1/16's or even 1/8ths. Will this reduce revenue and market, yes. Make it more solid yes.
Ah, I suggest you check with your sales department. I am willing to bet you will find the most likely people to buy shares 1/4 or larger are those who previously owned cards, or smaller shares.
Gotta let them stick their toes in the water to find out just how warm and comfy it is!
