I enjoy watching dumb animal greed get bitchslapped by the Invisible Hand. Market forces at work, what's not to love?
Maybe the people who got in at <$10 and held the entire way through because they thought $600, $800, etc. wasn't enough -- waiting for $100k/btc or whatever ridiculous prices bulls we're calling for during the big rise -- could be considered greedy, but the guys who bought at those prices were actually quite generous in their donations to those who bought at single/low-doubles and had the sense to take profit along the way.
$100k is still within the reasonable realm of possibilities... and merely b/c people are making these kinds of claims does NOT mean that they are tricking anybody or attempting to trick anybody.
Now if we attach probabilities to various possible price points, then some predictions are going to be more outlandish than others... but none can really guarantee the future, so that is a bit much to attribute some blame to people who are more bullish in their predictions regarding the height of the price rise and the speed of the escalation.
