I am TRX holder too, but i believe it's not scam coz it just happen that most of it's supporters are in korean exchanges.
Tron is shit, it is upto you to believe in this project or no. I have been holding some of them, but i dumped them all because i do not even believe in a single word of Justin. It is a mess, it is just an entire project with only 1 developer.
1 Developer? How fucking stupid can you get when hes clearly mentioned a bunch of recruitments already?
Maybe you have a look at the Github repo? There's one regular contributor and maybe 2-3 others. Very few updates, when i last looked end of last week there hadn't been any for 2 days. Announcements for team members joining recent dont impress or cover the fact this project went to market with a real team involved. Justin Sun himself is no developer, graduate in history. He's a manager and marketeer, maybe a damn fine one, but certainly no CS engineer.
Oh yes, and that Ripple connection, a Chief Representative for the same period he was chairman and CEO building Peiwo? The man must never sleep, like to have a couple projects on the go and will probably get bored of Tron before it delivers.
