Everyone should actively avoid anything even remotely associated with Justin Sun; he's infamous for being not only sketchy, but incredibly hostile.
Note that he used user funds on Poloniex and other exchanges to perform a hostile takeover of the Steem network recently and called the community "hackers" for speaking out against his tyrant ways. Speaking out on Steem will now get you censored.
this is Justin's usual marketing moves and everyone is already accustomed and everyone understands that if Justin San does something like that, he will bring a lot of money to the holders of his coin
It doesn't sound very decentralised when a certain individual pulls of a literal heist to steal the network and centralise it. Justin Sun is nothing but a tyrant that throws marketing around and baits in utter idiots that are new to crypto.
Note that the community literally forked into a more successful chain away from him and the Tron Foundation, and Hive remains decentralised. Not everyone gives a shit about money in this space, crypto was created to liberate and escape central authorities, not fall down and worship them.
"This is Justin's usual marketing." If you find it accepted to takeover decentralised chains for your own gain, you're here for the wrong reason, and I'm completely certain that you would not be okay with one individual 51% attacking bitcoin and taking control of it, telling you what is going to change and how. That is exactly what he does. He's a piece of shit scammer.
