Yes! A long term investment is just the best for Tron project because it appears that Tron want to be stable, looking at the market prices situation. Tron has been maintaining price stability for some time now, and it's coinmarketcap ranking is encouraging in 2019.You can
invest on tron if you wish to do.
I already invest in tron in the January and still invest now especially if the price is down. The price of tron is low right now, and I can buy a lot of amount of tron while I have a chance to make a profit later. I think tron is one of many coins that potential to increase in this year but it needs to wait for the right time to go to high price.
