TRX is fuel for USDT
For an arbitrage trader the point of TRX is not its own price. The Tron network is the most-used channel for moving USDT between exchanges, and the fee for that transfer is paid in TRX (or through "energy", which is bought with TRX).
So anyone shuttling stablecoins should keep a small TRX balance: without it the transfer simply will not go, and hunting for a couple of dollars' worth of the coin while a route is open is the worst moment to do it.
Trading TRX itself
As a traded asset TRX is liquid and listed almost everywhere. Gaps between exchanges are moderate — this is not TON or a small altcoin. But moving TRX costs pennies and takes seconds, so even a thin percentage can pay for itself.
What to keep in mind
Exchanges set different withdrawal fees for TRX, and on a cheap coin a flat fee weighs more than it appears: one TRX on a coin worth fractions of a dollar is a meaningful slice of a small transfer. Judge the absolute fee against your size, not the percentage.
And do not confuse TRX with USDT on TRC-20: the first is the Tron network's coin, the second is a stablecoin that travels over it. The fee is paid in the former; what you usually move is the latter.
Methodology and principles of analytical processing
Forming and structuring the data
The analytical system brings disparate market information together into a single structure, accounting for the specifics of trading directions and the individual characteristics of each platform. That keeps the presentation consistent and the key parameters comparable.
Criteria for forming the results
Forming the analytical selection takes into account the completeness, availability and reliability of the source information. Parameters that meet the established processing and confirmation criteria are included in the calculations. Insufficiently substantiated values are not used in the final results.
Currency of the analytical information
The information presented is kept current through regular refreshing and reconciliation of the analytical parameters. How often that happens is determined by the nature of each category of data and the way it is processed.
