Honestly I took a gamble and put some of my PTS in Bter. There is a very short window in which we convince the rest of the market that BTS is worth $1000 each. I'd rather have it on the exchange at that instant then wait a bunch of confirmations. Hopefully I won't get Goxed.
I've got some PTS on Bter also, but I don't see why you think it is such an "at that instant" crisis/opportunity if bitsharres blockchain won't even be launched until March 15th (ides of March)?
It wouldn't matter, what the release date is, since all coins traded on exchanges are iou's. So they could allow trading BTS iou's right after the snapshot.
It says BTS (read IOU) will be added to user account, after that PTS will start trading again. It doesn't make sense to hold off PTS trading till the ides of March.
