If you do the arithmetic, yes there will. At any rate, you don't need to be a millionaire to do venture investing.
At the rate FB is falling, it will be worth less than 12 billion in 3 months.
It's these kind of forward projections that cause booms and busts, ie. people assuming that housing prices will increase at a steady/regular rate over time. Just as we saw that this doesn't happen in a steady way, nor will facebook steadily decline over the next 3 months.
