I've seen that Chinese blockchain platforms are often forgotten by the community over time. It's mainly because of the lack of a strong marketing/promotion strategy. That, and also the fact that they're poorly innovated compared to other projects. TRON used to be "shilled" by Justin Sun in the past, but that wasn't enough to propel the coin's price all the way to the moon.
Developers aren't interested in building on top of the TRON blockchain these days. What's keeping it alive are none other than stablecoin transactions. If it wasn't by that, TRX would've been dead by now. Surprisingly, Binance has a large stake in the TRON blockchain. Perhaps that will keep it running for a long time? With competition getting fierce each day, I doubt TRX will survive. I'd steer clear from it just to be safe.
