Gox's 200,000+ btc is going to be liquidated soon, and that could be bullish or bearish depending on how you look at it. Some people view the recent positive assessment by financial analysts as bullish. I don't really see much on the horizon right now that would draw the masses that we'd need to go from $500 to $5000. The average person who had heard of btc has only heard negative things about it; hacks, stolen coins, drugs, nerds, etc.
We don't need the masses to get to 5000/BTC. We only need a few hundred million dollars of demand, and that could easily come from a single person (oligarch, sheik, etc.).
So a few hundred millions is going to raise the market cap from $6 billion to like $60 billion? Just doesn't seem very plausible to me. We'll need more than a few adopters to reach such a valuation. I don't even think bitcoin is ready for the masses. Maybe 10s of thousands of people lost coins on gox; imagine if we had mass adoption and millions of users lost money. Btc would come crashing down. Btc services need more robust security of decentralization.
