(1) This is one requirement for a bottom, similarly as everybody saying "up" is a prerequisite for a top.
(2) I have developed a wonderful proof that this is not true, but sadly my time does not allow to elucidate.
(3) Actually it seems that ask sum is drying up and there is very much (15k) bids in 400-470. Anyway these are easily manipulated.
(4) As well as their coins. This is typical for a bottom.
(5) I don't believe there is any additional "drying up" left in China. If someone wants out, he is already out. If someone wants Bitcoin, he is in.
(6) It takes 12-24 months on average from hearing to acting. That's why the upside will be so explosive (like 2013/1-4 as a result of 2011)
(7) Yes, in the bottom the news reactions are bad no matter what happens.
(8 ) Every day we go lower, there has to be new sellers selling a growing number of coins to satisfy even stagnant demand. I would not bet it happening indefinitely.
