The same link you post says:
"Anybody who tells you that Tron is a scam obviously has a hidden agenda and so do those who are quick to defend them. Dont follow blindly any of them and make your own research before you buy digital currency on cryptocoin exchange platform.
Lets keep an eye on Tron and see where this project leads us. For now it still has lots of opportunities to achieve."
So, true the whitepaper issue, but I wouldn't dismiss an opportunity of big gains just for that.
Let´s be cautious, but lets be bold too!!
Trx went from 0.002 to 0.05 in a month or so... that's profits right there!
