This is the end, folks!
Agree with you, this is obivously the end. Dev has gone and no active anymore since 14/06 or almost 1 month. Sell your reamining coin, this coin is dead 
PiCoin era is endbut to sell Picoin at current price can't give you nothing.
Why not just hold it?
Hard to say, if dev still no show, then it is better to sell at current price than lower price in future...
