As i know there is nothing to do for it.Before de-listing a coin exchanges announce it and give time to make transfers. I think you have missed that announcement.By the way Best thing is keep going on without worries.
For his own issue, I think its trading that was disabled and as at the time he made the post, they were yet to delist it, since they have not delisted it, if it’s an ECR-20 token, he can still transfer it to his ether wallet and then send it to another exchange where he can sell it as quick as possible.
It is not all exchanges will make that decision at the same time, but the moment an exchange plans to delist a coin, then that coin is already having issue and won’t be long before other exchanges too get tired of it, so before it gets to that point, he can just transfer it to another exchange and sell it for bitcoin to those who would later be a bag holder of it.
