Almost all the old cryptocurrencies are on the rise now, not only TRON, but BNB, XLM, ETH and a few others have also grown and are known by many people in the crypto space, so I think it's a very good and natural thing to happen.
I do not think so, but it is the end of many cryptocurrency projects. Take, for example, most of the currencies that were in the top 10 list, relegated to a minimum position.
What keeps tron alive is the dollart, which will soon expire when more platforms start offering lower fees.
