beta bittrex distribution tab is showing that too many are holding coins on exchange and just don't care at all about this coin being PoS.
 conclusion : too many day-traders and P&D'ers have bought this coin and, since we all know these type of guys aren't known for their patience, we can expect some slow (or fast) dumps occuring through all the day. i would say: hold if you believe or sell if you don't have the patience to wait and don't want to lose too much.
