There's no limit to how far TRX can go. The same applies to any other cryptocurrency on the market. If there's high demand for TRX on the market, you can be certain that it'll go all the way to $1 per coin. Otherwise, its price will stale. Technically-speaking, TRX is better than Ethereum for "De-Fi" and NFTs. That's largely because the TRON blockchain has blazing-fast speeds and ultra-low fees. If BNB is worth more than $300, then TRX can easily reach $1. We've already seen how useless coins went to new All-time-highs because of the bullish market. How long will it take for TRX to reach $1 is an excellent question. As long as the Blockchain is useful, nothing else matters. Just my opinion 
Despite having those advantages TRX hasn't got much attention of investors. TRX is better than Ethereum chain but Binance smart chain have much popularity now. I have observed a lot of new projects (DeFi & NFTs) and found that almost 90% of them launching on binance smart chain platform. While TRON blockchain is rarely used by new project team. TRX will take long time to reach 1$ if this trend doesn't change. Most of the useless coin price increase and decrease in the same way. But TRX have good support in crypto market.
