You need to withdraw those coins. They get delisted, and the wallets are maintained for a few weeks, and after that you lose the coins. So transfer them to an exchange where you can sell them.
They will be delisted how about the coins in the exchange?
Lets say if i am out of my place for weeks.
But my wallet held 5000 of x coins which are going to delist
After coins is delisted, can i still withdraw it?
Maybe poloniex will give a date line for member to withdrawal their coin, but for more sure sent the ticket support asking about this, poloniex support very active and respon the ticket in fast.
