Wrong thinking when a big coin like TRON is too dependent on Justin Sun, I think when he came out the work shift was done perfectly so TRON will continue to prosper, I also never doubted the future of TRON even without Justin Sun.
That's not the question here.
The question is about USDT and not TRON, but TRON I think will probably be harder hit with Justin leaving than USDT.
USDT will falter as a matter of time regardless of what platform it is hosted on. I simply don't believe in their fractional reserve model.
