You bought the tokens because you believed you could make some good profit from it. The hack situation is no one's fault but maybe the exchange its listed. The token will definitely list on more exchange, just keep the hope alive
If the exchange is hacked and the team has not managed to list the token to a new one, then doubt that you will ever get back your investments.
What do you think I should do now?
If the token or coin has no price then nothing can be done. Because the token is valuable if there is a price. Exchange is the most important thing, if the token you have does not have an exchange, it is useless. We can only wait until the developer signs up for another exchange.
What he can do is just wait for a miracle to happen that the team will list it to another exchange. But if not, he can't do anything about that token.
