The OP didnt sell shit.
Obvious way to try and make the bitcoin price drop down so he could buy in lower.
If he did "sell", I'm sure he had like .005 bitcoin anyway, so .00025 bitcoin sold. wow big deal.
good job jumping to a conclusion. how do you know he didn't sell the coins? you could be right, but you could also be wrong. no need for armchair detective work.. if you aren't actually doing any detective work.
This is all just a play by the OP, anyone who was serious wouldnt find the need to make a thread about it, look at the title: "I am selling half of my Bitcoin holdings because of Ghash", If he actually sold the coins, he would of changed the title also, and his original post.
I conclude he hasn't sold the coins, and if he has, it is a very very insignificant amount...
