My guess for the bottom, if I am realistic: 12 $. Maybe 15, maybe less ... Maybe even less than 1$.
I'm not going to argue about most of your post. But since you're new, I want to provide a history lesson, along with an argument as to why I consider <$1 to be an extremely unlikely scenario.
This is a chart of the end of 2011. After the first Big Bubble popped at $33/coin, the BTC market was in a downtrend. Many predicted, on this very forum, that BTC was dying and it was just a matter of time.
The price got to $2 in mid-November. At that time, Mt. Gox experienced the biggest trading volume ever - a record that remained unbroken for eighteen months. For several days, the market threatened to break through $2/BTC. It did not. Even in the face of a bubble that brought the price above $1/BTC and had been slowly sputtering out for six months, even among doomsayers who believed with all their hearts that the Bitcoin experiment had failed and prices like $30/coin were a one-time event, never to come again... even in such a climate, people wanted BTC for $2. People wanted them enough that the price never crossed that line. It was an insurmountable foundation of support, and from there the price began to climb again.
Now, the BTC price has beaten the previous bubble - market participants know that high prices were not a one-time opportunity. There are major online services that accept it, other than Silk Road. There's been media attention. In today's environment, what could possibly hurt confidence in the currency any worse than it was hurt in November 2011? What could possibly make people less confident in BTC than they were a year and a half ago, when they bought in with all their might at $2 a coin?
Don't get me wrong; I think the price is going to keep falling for a while. When I try to rule out my emotionality, the math of it looks like we're going to either $30ish or $11ish as our nadir. But given what happened in the latter days of 2011, I cannot imagine what would force the price below $2/coin that wouldn't have done it then.
