There isn't news about TRON but it's pumping yesterday. Quite random but so is the BNB today that touches a new ATH at around $750. The top altcoins have been climbing since Nov this year, I guess it's not surprising anymore because this is a bull run already.
* Tron has its own stablecoin in USD better known as USDT - TRC20
In short, every L1 token can potentially go 100X whenever there is stablecoin with them. This is also the reason why XRP has been going well recently because of their RLUSD.
