Tron a scam? Do you mean you lost money buying at the top? So many people are quick to call something a scam just because of their own misjudgment/timing. I think Tron is a solid project and will come through soon!!
Its a scam because
TRON plagiarized it's whitepaper and various other things from other coins.
TRON has no product, it is essentially vaporware at this current time.
TRON (whether that was the CEO or his developers) unloaded a massive amount of $$$ after it ran up and idiots are STILL putting money into it.
I think this is reason enough.
