The amount of people interested in Bitcoin combined with the supply will not allow BTC to drop to single digits ever again. Or double digits IMO. I would buy so many if it did, just like everyone else would.
The law of supply and demand can't be beaten.
Most of people don't want to buy btc to play poker or satoshidice, they just want make profits. And if they can't make big profits anymore, they'll leave as the tulip system did 350 years ago...
Bitcoin euphoria just reminds me of Second Life hype. But Second Life is not dead, there are always people on there. Bitcoin won't die too. It follows the same way.
