Tron is dead. So far nobody came with 1 argument that shows the development of tron still to be on going in any way.
My response isn't enough for you mate? You're talking about DApps and I've already answered your question with an answer regarding DApps residing on the Tron network. Now it becomes clear that you are actually questioning the development of the Tron network ecosystem as a whole. Did you know that Justin Sun issued his own Stablecoin (USDD) which originally ran on the Tron network? That's part of the development in the Tron network. For complete information regarding USDD (Decentralized USD), you can find out on the
official website.
