I too have been suspicious of TRON, since I first heard about it. I don't know the real-world use of TRON. I don't like coins that are hyped up. I like coins that have a clear real-world use and utility. I have not and will not invest in TRON. Something about it just seems suspicious. I could very well be completely wrong, but I'm just going by the impression that I have. Thus, I will not invest.
It's ok just do your own search very well and if your feels doesn't look good on Tron then don't invest on it. But I tell you Tron is not a scam and has a very big potential for a long term hold not a short term. Just my two cents.
