Its the cryptsy bots I think.
If you look at the past history, a lot has been bought at around 200 sats in the past week.

If you can hold your coins a bit longer , may be you can double your returns.
I would transfer the coins to cryptsy and keep it there, if you want to profit from the next pump.
(Cryptsy sometimes tend to increase the confirmations to a high number, before they start pumping, so that they can see the whole market position, and they dont have to pay any trade fees either, which makes it easier for them to pump and dump)

Waiting to see how it pans out in the coming weeks
