There was a strong selloff of POT in early May. I am going to go on a limb and say that the halving was probably being seriously discussed in Reddit earlier than it was here. I'm not going to say one is a direct result of the other, but letting it ride out a little longer would have been a smart move. The halving was announced May 9th in this thread. At that time the high for the day on Mintpal was 885. Before that, it was breaking 1000 on a regular basis, with the highest pump hitting 3700. I sold nearly all my holdings at the time at 3500-3600. My team did the same as we watched the pump. Hopefully others did the same.
Per block value of POT before halving < per block value of POT after halving. To be as profitable as before, the price would have had to have doubled. Below is a chart of the life on Mintpal. Blue is the previous floor, or the minimum profitability. To be as profitable as before, the red line(the new floor) would need to be where the yellow line is. We went into the previous profitability on two pumps, but it was quickly pushed back down. The charts don't lie.
