I always felt the market cap should include all 21 million BTC and not just what is in play. That being said, when I look at Bitcoin as if it were a publicly traded company, I have a hard time believing something with such disruptive potential could trade with a market cap as low as it currently is. I think that an upper target of $2,000 per BTC is not out of the realm of possibility within the next 2 years. I also believe we may retest $200 first, and with enough negativity possibly even down to $80. Will we see a swing down to $80 and then to $2,000? Probably not, but I would be surprised if we broke above $2K or below $80 without either a country accepting BTC for tax debts, or the blockchain becoming compromised. We're definitely closer to the bottom than the top at this stage.
When Ross was arrested the price crashed to ~$80 and then went to over $1,000 (on gox) within days.
Going back to ~80 and then to 1k again would not be out of the question, 2k might be pushing it a little bit (at least over the very short term).
Who knows what might cause this kind of volatility......the DPR trial is coming soon
