Re: Who stands to gain from such an Exchange being created?
It seems that people who can bet on this exchange going bust benefit from its creation, but that may not be legal either.
Anyway, to most of us it seems that "information" within a stock market is mostly imaginary. Particularly day-traders who hope to read the economic future in the rather random previous daily fluctuation of a price, having been put there by collective activity of people who don't know any more than you do.
Also, does anyone else recall hearing about at least one small enterprise which was shorted to death or nearly so by a powerful speculator - an actual wealth creator crushed by the great money casino? I think it was either in the IT sector or maybe pool noodles or a new kind of table fork, I don't quite remember. But a boon to humanity nevertheless, wasted.
