Setting aside the Mainet launch, the main disadvantage of TRX is the massive supply of 100 Billion. With the recent coin burn of 1 Billion TRX tokens on June 26, the total supply has dropped to 99 Billion. Now that the Tron foundation has locked 33.25 Billion TRX tokens till Jan 1st, 2020, the circulating supply has clearly reduced to 65.75 Billion. So I am expecting a price jump anytime soon because we all know what happened with Ripple when it locked away its tokens.
