I have been trading tokens for some time. But what if all of a sudden they stop the token from a token exchange?what a closed token says.And will I ever get the closed token back? Is there a system? Tell me if there is.
If you are talking about tokens or coins getting delisted from an exchange, then you will always be warned few weeks ago (or at least days ago) before they remove it. You will receive an email or notification on their exchange about the token getting delisted. You will be given enough time to withdraw your tokens. Even if you missed the time frame for some reason, you can always contact their support and they will help you manually withdraw your coins or tokens to your address. At least a well know exchange would do that for you.
