There's room for doubt about the existence of the coins on the exchanges we already, if those unscrupulous bastards get involved they'll certainly try to turn it into a fractional reserve system. Screw that, distributed exchanges ftw.
Btw, the real target here may be the hashrate, force it low enough and in theory miners should shut down and the whole network slow to a crawl... except it doesn't, both miners and hodlers have a lot more balls than whatever generic investor profile attackers are using, the hashrate keeps building and cheap coins are being scooped up by the thousand.
If that's true, that means there are less actively traded coins on the market than we all think, which means the price is too low. Supply and demand, such a simple concept and so difficult for so many to grasp.
