Don't ever let go of Tron because like China, it is in fact the sleeping Giant Altcoin that soon enough will skyrocket and will offer it's holders a good profits.
I am holding Tron TRX over a couple hundred of TRX coins so I know that soon enough I will be getting more profits and tend to let Tron do the rest.
One of the things I like Tron the most is it's transaction speed and it is the most factor of a Crypto that transaction speed matters because in the near future people would use Tron for their everyday lives.
