Tron anyways had no future to be very honest, it used to be a good project and even people had too much expectations from the project over all but now the whole chain is just used primarily for Tether transaction because it's way cheaper than any other blockchain. I don't think future of anything would be in danger you anyways don't need any major advancements or inventions to run USDT on your chain, and also the team wasn't doing any major developments.
