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 number of follower is not the right basis to determine whether the telegram group is legit or not because it’s easy to increase the member of telegram channel by just adding bots on it through SMM with cheap price. It’s better to go on the official website and browse on there social media account to see there official telegram channel. It’s better than sorry just by doing shortcut just to find the group easily.
