I think enough people have now stashed money in BTC that they will step up and buy to keep the price stable when it falls below $5. This is to protect the value of their stashed funds... Just my $0.02.
This would be very interesting if we could prove that. The same psychology exists in the gold & sliver bullion market as well. You see it happen when the "paper" price falls below the physical price and people go to purchase the precious metal but you can not purchase it on the spot for that amount. It happened when sliver dipped below $10.00 an ounce (from $16-18), you could not get your hands on it for less than $16 plus premiums.
