The snapshot of PTS ownership for receiving Bitshares was on 2/28, so there was a run-up in price during the week or so before. After this was over, on 3/1 there was a big sell off, and some drifting downward in price since. I just picked some more up yesterday to take advantage of the low price, since it will be used for more genesis blocks for Invictus created and other Decentralized Autonomous Corporations (DACs).
