Were there any stakes still attempting to trade on the AE when the deadline fell?
Did the price go up, or was it crazy, crazy firesale prices at the end?
the price went up to 99,999 NXT per stake. then after the portal closed there were still some open buy orders still up even though all the sells had been taken down. somebody who realized they couldn't redeem their NEMstake dumped and took the NXT from people that were stupid enough to keep their buy orders up.
Even now there are still some buy orders up so we may still see some more transactions on AE even though the people that have the NEMstake won't be redeemed. Those are lost NEMstakes now.
