See, people keeps saying that, but no one really qualifies what they mean.
Here's what I see:
BTC payment services getting hacked (bitinstant), BTC wallet services being hacked, Lag on the exchanges grinding trading to a halt and killing liquidity, an overinflated price driven by media hype and people looking to get rich quick, an overinflated blockchain that may or may not contain child porn (or links to child porn), an economy driven primarily by drugs and grey market goods, etc, etc
....and thats just the tip of the iceburg.
Frankly, the fundamentals look like shit.
