Many people see “TRON fees above 1u” and think they’re expensive, but for large stablecoin transfers, this cost really isn’t much. For example, when transferring a few hundred or a few thousand USDT, the on-chain cost of 1–2 USDT is still far cheaper than Ethereum, so more users naturally choose it.

The main groups that use it are probably these categories:
The first group is exchanges and quant/arbitrage funds. They need high-frequency transfers and what they’re after is speed and saving money.
The second group is OTC and stablecoin users, especially those who only care about sending and receiving USDT.
The third group is cross-border transfers and small remittances, which are more convenient than banks and traditional channels in some regions.
The fourth group is merchants receiving payments, gray-industry activities, and capital flows—this chain really does have plenty of that too.
TRON’s strength isn’t that its technology is “more advanced”; it’s that it has nailed the most in-demand scenario: “stablecoin transfers.”
Many people don’t use it for complex applications—they just treat it as a USDT highway.
