I expect OkEx coin to have notified their customers about the proposed delisting via the emails on their database for the sake of those who won't be on the forum to read and those who believed in their wildest dream they are holding long term for them to turn massive profit and not involved in day to day visit of the platform. The best approach is to liquidate if there is no plan for such coin or move to another platform that is not ready to delist.

I can actually relate with something like this when the exchange I have a coin just came with a notice that they are delisting but the coin would be available for withdrawal only for them to just decide to deactivate withdrawal without even notifying and that's how I lost out that the coin later became a worthwhile investment.

I have the same impressions, exchanges don't need to pay anything to the devs when the coins are de-listed. If my memory serves me right, one criteria the exchanges used to delist a coins is lack of trading volumes or developers abandoned totally abandoned their coins. Take note though that TIO is still. very much a active coin, and they even have their own trading platform now.

this is their omission, i not yet receive mail about it

Did you really understand the topic? OKex is delisting the coins which means that it can't be traded anymore. Why are you buying coins when you can't do anything with them and at the same time, you already lost your money when you get those dead coins.

You are already informed when the OP open this thread. So you should do appropriate actions on your end already. I'm sure that OKex will mail blast its customers as well. They are one of the top exchanges, so I'm sure its a priority to let all their user based updated with the news.

Even if they're still being traded elsewhere, I wouldn't suggest that risk. It's too much trouble getting into a coin that everyone else is abandoning. If the exchange is delisting multiple pairs, it's for a good reason. No one is buying it and it is becoming useless.

Too many shitcoins emerged last winter and we are starting to see the decline. They couldn't have all survived through such an aggressive market, so we can see they are getting weeded out one by one. Hopefully this is a form of evolution and more reliable coins can enter the market as a result.
