This should be obvious... They gave the users 1 month to withdraw, after this date, people will no longer be able to access these coins, so Poloniex can then do anything they want with the RIC in their wallets.
If they decide to dump the 10 M coins, we will pass a really hard time in the following months...
So, after completing successful update and comeback, there will be huge pump and then dump. Nothing will change, because all people are same. Just think about this, that someone influential will have interest in pumping this coin again.
