this is true, withdrawing USDT via tron network is very economical right now. and other TRX-based coins, even the TRX itself. and since eth has still ridiculous fees, a lot of crypto users are appreciating other networks like bsc and tron. so right now, they are enjoying the market as the opportunity is really at their doorstep. now, it is up to these networks to be aggressive with their marketing and continue the interest from the community.
TRON is very good for day-to-day transfers and withdrawals because of its high performance blockchain network. In some cases, transactions are free making stablecoins extremely practical on TRON. This makes TRON better than Ethereum for day trading, and decentralized applications. People are getting tired of ETH's high fees, so they're pouring money into competing chains like TRX and BNB. $0.12 per TRX is nothing if we consider the features it provides. Who knows if TRON pumps all the way to $1 in the not-so-distant future?
Nonetheless, I believe that TRX's rise may not last for long if other projects fare better in the long run. Right now, Binance Smart Chain (BNB) is getting all of the attention in the mainstream world with "De-Fi" applications that can't be ignored. PancakeSwap is extremely popular in the crypto/Blockchain space, with comparable liquidity to that of Uniswap on the ETH blockchain. Tron's Justswap is widely unpopular, although it serves the same purpose as both PancakeSwap and Uniswap. It may turn out to be that the recent TRX pump is only temporary. Not even Justin Sun shilling TRX on Twitter has made the cryptocurrency reach higher prices on the market. With his efforts, TRX would've been worth $1 by now. At least, the TRON blockchain is alive and healthy as ever. Just my opinion
