Saying this implies that preorderers knew that bitcoin would be worth $244 only 7 months after buying the rig. Sure it would be a better idea in retrospect but nobody has perfect information. If everyone had perfect information all the time, then yes, no matter how you cut it, all BFL preorders would be a bad idea.
This BFL shit is becoming worse than the Rebublican-Democrat division. Everyone wants the same thing (MOAR GOVERNMENT!) with very slight differences and they hate each other for the slight differences.
Stop trying to make people regret using their currency as currency. Spending bitcoin is the only way to ensure its long term success.
