There is no market manipulation, only people like me getting out... I dumper around 25k XC only yesterday. That was my last stash. I had enough of this, since Blocknet clearly killed this coin on a med-long-term approach. (This is only my point of view).
there are few strange things which notice that even the blind!
1. i saw your(if it was your) sell on Bittrex.
1.1 why you sold it all at once without even trying to place the sell order? This's good amount and great price!
1.2 why the buy order was excatly(+- few coins) the same as your sell order? In theory this is a great match!
2. after your sold you wrote on BTCTalk: i'm sad but I'll compensate it soon don't worry
2.1 if the guy lost 25 btc what you think he'll write - I'm so sad

or !@#$%
2.2 usually if someone lost much this thing makes him an aversion and trying avoid but you are still here speaking with us as if nothing had happened.
I bet you are the bait of Dan and Co!
