Volatility is good for growth, as long as nobody with a lot of bitcoins decides to spike it clear to the ground. I don't know why anyone would do that.
This looks like a foolproof way to skim the gamblers. And lay the foundation for sustainable growth. Volatility is poison.
It's only foolproof if you have tons of bitcoins to throw away (it would take over 1/8 of all bitcoins to make it to 0.01, assuming only visible orders on mtgox). Sustainable growth is happening... it's just won't be smooth so long as 1% of any other market can move this one by 50%. Bitcoin doesn't exist independently from the rest of the world's economics. Some of the best medicines are poisonous in larger doses.
