But to insinuate with absolutely zero understanding that the creators of bitcoin did this to get rich is just plain nasty. Maybe they did want to get rich (in dollar terms) but there is nothing obvious on the block chain that proves that they cashed out. The argument seems to be that they can't cash it all out so they are waiting for something. Well, they haven't cashed anything out yet as far as anyone who looks at the block chain can tell. It's already possible to cash out $5-$10MM easily over bitstamp which would represent a fraction of their holdings. Why not do that and make sure your future is taken care of? At least that?
Furthermore, for several years it did not look like bitcoins were going anywhere. However, the people behind it continued to work on it, and still continue to do so, but under much new pressure because suddenly they are evil ponzi dealers.
Applying old school economics and psychology is great, but I must ask this question. What kind of value appreciation did gold see when people suddenly for no reason decided that it was worth a lot? Following this value appreciation did people not use it as a means of exchange as well as a store of value? Why can't bitcoin be thought of as gold 2.0? We started valuing dollars, pounds, euros, airplanes, cars, oil, and those didn't exist for much of human history.
Bitcoin isn't like something we've ever seen before and that includes Ponzi schemes. It may end up crashing and burning and it may end up doing really awesome stuff.
I just wish the naysayers would come up with better researched arguments instead of this crazy witch hunt.
