Likelihood of this being the one to gain approval?
I personally think it's nil. Nothing's changed fundamentally from previous rejections.
It looks like an all round better proposal than the Winklevii, insurance is present for one, but it comes down to the same old insoluble thing of the markets themselves being too bent and staying forever bent.
It'll be a fine surprise if they do go for it.
I agree.
Naturally, Im a pessimist but trying to be neutral on my view with this & like yourself I dont see whats changed in such a short amount of time. The market is still volatile & can be manipulated by large players (you could say that about most fiat stocks though re: governments meddling for their own good).
