I agree with what he wants that entirely relying on the U.S. market will lead you to more uncertainties that could negatively impact your life. I am curious about what he could do with his influence in the crypto market. It's no joke that he has a lot of things that have been done in the past, but I think it has helped crypto somehow.
Real influencers who understand and involve in crypto technically do have big impact when they want to show their power. Justin Sun is a guy like that and similar to Charlie Lee of Litecoin years ago. Charlie Lee sold all of his Litecoin and now Justin Sun wants to retire from TRON.
It is something we have to accept. Decentralized projects will have their founders leave, retire etc. We already heard that Jack Dorsey might leave the CEO position of Twitter.
For the growth of Tron, it would depend on who will lead it for sure.
Overally, crypto projects should be decentralized. They should be developed and operated by community, brains from community should be bigger than brain from a single developer or a group of core developers. Network operations, decisions should be made by community votes, exclusively holders and their vote power will be identified by weight from number of coins or tokens they are holding.
