This is just another confirmation that the days of TRON are numbered, it is very unlikely that it is going back to its former glory so people need to be very wary of investing in the coin, now that being said this is not going to affect USDT at all, this is at worst just a small obstacle on its path and nothing more, USDT does not need the TRON network but the TRON network needs USDT, which means that if someone is depending on it for their USDT transactions now it is the time to rethink this decision.
