What some people fail to realize is that supply and demand are actual market forces, they aren't just imaginary. My friend now has 6MM he just sold @ 1.4 because he was offered 1.7 and decided to hold out for 1.8. My point is, when you ascribe these "values" you should maybe clarify that these are your utopic values and not necessarily what is happening in the real world today. AmEx can be "worth" 5 cents if you use it yourself, but no one is talking about that here.
Who's arguing with your point? This works very much like the stock market. Your friend sold at 1.4 because he got scared that it would go even lower due to the mad rush of point sell-offs. (unless your friend urgently needed the money?)
Dan's point was that there is no reason to fall for the mad rush, but rather to give it some time to stabilize. It won't go back to 1.7, but it may go to 1.5-1.6.
