However, the counterweighting factor is the risk associated with holding options on an imploding exchange. That alone isn't enough to make me execute yet, but now that I consider I am also trapping the money of the people that wrote me options on BTCT, that is enough to compel me to execute the remainder later today.
Sorry, by the way. I don't enjoy taking people's money. At least you did a little better than you would have if you bought another share outright.
