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?
No, you can't withdraw those coins after being de-listed that's why the exchanges give a period of time for holders to withdraw their coins. If you see any of the going-to-be-delisted coins, you will find a message warning about withdrawing them before the time set for the de-listing process.
