It is a very good efforts by Sun so far on the Tron project. Few years back he launched the Tron blockchian and left the Ethereum platform, and today, the Tron platform is gradually gaining good ground on the crypto space. I think the Tron project will definitely grow much more than the present.
As for the Tron price, I think the Tron (TRX ) is massively own by big investors, and in such situations, there may be very slow price increase because of low trading volume in the market. The larger volume of TRX coin on the market is controlled by these big investors who will sometimes cut some profits from any slide prices increase there by slowing the market prices. This is just my opinion.
