As other users have said, there's no proof Justin Sun is involved, in fact, If I was interested in something and realized JS was involved, I would do a 180 and walk away. Haven't you seen how he is wrecking his own projects? The guy is a criminal in his own country... come on...
I also checked the team page and I don't see Justin Sun or anyone working in the TRON project their team page shows this
Team
The JUST foundation has a dynamic and elite team. In the technical team, 50% of the employees come from alibaba, tencent, IBM and other world-class Internet companies, with rich experience in product design and development.
This is their claim but how do we know their credentials, if there are no names in their team page, I cannot trust this kind of project.
You're looking for credentials and certifications from the guy that copy/pasted a whitepaper, centralized his main coin, managed to get pewdiepie off of dLive and wrecked the decentralization of his latest acquisition, Steem? He's a scammer, a con-man, just smoke screens and dirty communist money on his back.
