Good observation I'm a big fan of TRON, fast transactions and cheap are the two main reasons in fact I have more transactions on Tron than any other coins, if I want to trade my coins to fiat my go-to coin is Trx, on gambling sites I'm playing Trx is also my go to coin, they have potential for new projects that are coming out but unfortunately, they are beaten by Binance and other newly launch chain, but I still trust Trx, it's still has a place in the top 50, on being the next Ada or Doge we never know but it's a good candidate.
TRON is extremely cheap and fast to use, probably because not many people are using it. The number of dApps available on the platform is quite small compared to those available on newer, competing chains. I wonder why mainstream developers aren't building dApps on TRON, since it's practically as fast as BSC or Polygon (MATIC). In some cases, fees are even FREE if you had some TRX "frozen" for bandwidth/energy. Even USDT is available on the TRON blockchain and the experience is beyond compare. If more tokens and dApps joined the platform, TRON would've been among the top 10 coins in market cap by now.
Now with Justin Sun leaving the project, I'm having doubts whenever TRON will become the next DOGE/ADA or not. There's a lot of uncertainty with TRON's future, so I'd consider it a very risky investment. Unless innovation comes in, TRX's price could remain stagnant for years on end. Just my thoughts
