Hi! I have a question but first Im gonna tell you my situation. So here,
I received a token long before it was listed in an exchange. Few months later I checked the token on Myetherwallet (MEW) and it said that the contract address was changed or has been updated.
Does it mean that I cannot use those tokens with the previous contract address?
If the previous contract address has been hacked, then they could have changed it into another one and holders of the token would have to swap.
The same happened to TIO. (Trade) recently. Some tokens were stolen by hackers and those hackers started dumping the tokens on an exchange. So they had to make a fork, but halt transaction on exchanges (moist especially kucoin).
So, you can check the social media handle of the token, which is where they most times make announcement.
