This coin is not included in my portfolio, some of the coins in are popular altcoins but I did not invest them for a reason that is better than other altcoins.
It depends on the choice whether you have kept it for a long time? I know Tron has been chosen a lot but for me this coin is difficult to bullish so it is a bit slow in my opinion the movement in the market.
For the OP, do research, and what percentage of your investment will be allocated, this will make it easier for you to manage it.
Tron is a great deal for using the network but not the coin itself. Like for example if you want to send USDT to someone, using TRC20 version would be a lot cheaper, nearly free and you could send them thousands of dollars easily. This is what they are good for, any project that has a wrapped version of a coin that you could use in the TRC20 network could be great.
But, just because you could use their network, doesn't mean you should use their coin neither. Aside from that I agree with your assessment, doing your own research instead of asking people is a lot better, people just shill their favorites, and do not give proper answers.
