Usually, on inside buzz, you have to be a member of their community and follow their official channels for announcements.
Check out the development of their project and the movement of the price, I would like to remind you there is such a thing as fake news so better to check how reliable the news is and where it is coming.
Is this a kind of pump group that provides information about what coins will be pumped hard?
If so, then the group is just a manipulation group to trap many people into buying the coins mentioned, even though those who own the group have already bought them in advance before the announcement.
The pump group is just a waste group that harms many people.
