Indeed, I have been holding some of my investments in USDT TRC-20 already long time, and in general, when I withdraw my investments from cryptocurrency exchanges, I always withdraw my investments in USDT TRC-20, since the commission for withdrawing USDT TRC-20 is only 1$, and if you will withdraw through USDT ERC-20, then the commission is usually about 20$-30$, and in general, since the gas price on the Etherum blockchain has been very high already 2-3 years, then of course it is understandable why many people in the cryptocurrency field chose the Tron blockchain and not the Ethereum blockchain and this also applies to USDT.
