ya.ya.yo!
They are those people who know how to manipulate their sells and they know when to announce the hype so that people will gather and curious about what project they are talking about. they are one of those viruses in the crypto industry that hard to distinguished from the legit one. their strategy changes from time to time whenever their modus from the past has already busted. Therefore when someone is offering you something especially those people you don't know, don't rush to whatever they said rather you need to consider that there are some projects that don't really exist but just to scam their investors with some sweet words.
