What a transaction costs here

Every action on chain costs gas, paid in BNB rather than in the token you are moving. On BNB Smart Chain the amounts are small, which is not the same as irrelevant.

The short version

Gas is paid in BNB, so a wallet holding only USDT cannot transact at all.
The cost is units of work multiplied by a price in gwei, where one gwei is a billionth of a BNB.
We read the network price at 0.05 gwei on 6 October 2026, at block 125,965,545.
At that price a token approval of about 46,000 units costs roughly 0.000002 BNB, a fraction of a cent.
On a 1 USDT cycle returning three cents, even a fraction of a cent is a visible share of the return.

The arithmetic, once

A transaction consumes a number of gas units depending on what it does: a plain transfer is cheap, a contract call that touches storage and a liquidity pool costs several times more. You pay those units at a price quoted in gwei, and the product is your fee in BNB.

Because the price is set by demand for block space, it moves. The figure above is a reading, not a constant: check the current price in your wallet, which shows it before you confirm anything.

Two transactions, not one

Spending a token through a contract takes two steps. First an approval, which authorises the contract to move a given amount of your USDT. Then the action itself (a deposit, in this case) which actually moves it.

New users routinely approve and then close the tab, believing they are done. The approval alone does nothing: no funds have moved and no position exists until the second transaction is confirmed.

Why small amounts are still worth thinking about

Fractions of a cent sound like nothing, and against a 1,000 USDT deposit they are. Against a 1 USDT test cycle that returns three cents over seven days, two transactions in and one claim out are a measurable part of the return.

That is an argument for treating the minimum deposit as what it is: a way to watch the mechanics work end to end, not a way to earn anything.

What this changes about reading TurboLoop

No figure in the calculator includes gas, because gas is paid in BNB and the plan is denominated in USDT.
Keep a small BNB balance before depositing, or the approval cannot be sent.
A 1 USDT cycle is a test of the mechanics. Judge the product by it, not the profit.
