Ok i am not sure it is official pancake telegram being hacked or it was fake account from the beginning. I mean it has almost 238k followers. Now telegram showing scam along with it. And it's latest message asks for synchronizing your wallet for fixing issue which is clearly scam. So whatever the case beware of it.
The pancakeswap telegram group does not have 238 followers but the 78k followers are official so it's possible that you are included in a fake telegram under the name of the official Pancakeswap so be careful about this scam.
This must be avoided because telegrams are cattle of fraud everywhere, even those who DM first, we need to know a lot if it doesn't make sense to you then get out and report the group.
