There y'go again - worrying about that funny fiat currency when y'should've stuck with real money - STOP IT!
$85 billion per month. A little over $1 trillion per year at that rate. QE1 was $2 trillion all up and QE2 was $600 billion, so 7 months of QE3 is equal to the whole of QE2 and two years would be equal to the whole of QE1. Two and a half years of QE3 at $85 billion per month would be about the same as all the QE that came before it. They've been at it for 13 months already.
