Getting involved is risky - even if you are right (and I think you are), the price could still increase by a large amount for a long time before sense reasserts itself.

As Keynes apparently did not say: "The market can stay irrational a lot longer than you can stay solvent."

If you hit your trading / credit limits you could lose a lot of money despite being right in the long run.

And as Keynes definitely did say, "In the long run, we are all dead."
