Edward50, your observations of this player and his/her intentions are very poor/wrong. Price will eventually most likely go lower, but that has very little to do with this player. What you wrote is a fabrication of your imagination and your wishful thinking that bitcoin price should drop.
I'm in no way saying market will rally, I always said in my posts that I think bitcoin is a sub $10 product at its current use. But at this moment anything goes, a $300k buyer could show up just as likely as a $300k seller. Every time we get a quick pop from $7 to $12 on no news, chances are rally won't get far because nothing fundamentally changed in the game. Your sell signal is OK, everyone who bought bitcoins at sub $8.00 prior to this rally should be unloading at least 80% of the position, because right now it is more likely that in a week or a month market will again be trading at $8.00 or lower, but this does not make it a good short by any means.
