Anyone looking into "bitcoin wallet app" is really asking what a coin costs and how long it takes to move. USDT transfer fees come in two layers: the network fee, paid in the coin of the network the transfer uses, and any withdrawal charge an exchange adds on top. On TRON the fee is covered by energy and bandwidth or by burning TRX, on BNB Smart Chain it is paid in BNB and on Ethereum in ETH gas. The cheapest way to send USDT is usually the network both sides support with the lowest total charge at that moment.
How to convert BNB to USDT depends on where the BNB sits. On an exchange, a convert or trade screen sells BNB for USDT and shows the price and fee before confirming. From a wallet the owner controls, a decentralised exchange performs the swap on chain, with the network fee paid in BNB, and the price filled can differ from the quote through slippage. The USDT contract address should match the one published by official sources, because a name and symbol are easy to copy. Keeping a little BNB back covers later fees.
Why is my bitcoin transaction pending? A pending bitcoin transaction has been broadcast but not yet included in a block, usually because its fee rate sits below what miners are picking at that moment. Bitcoin adds a block about every ten minutes on average, and a low fee in a busy spell can wait for hours. Broadcasting the same transaction again never pays twice. A wallet that supports replace by fee can send a replacement with a higher fee, whereas a brand new separate payment can pay twice if the first one confirms later.

Why must the same network be chosen on both sides?
Coins moved on one chain stay on that chain, so a mismatch can strand them.
Why match the USDT contract address before a swap?
Anyone can create a token with the same name and symbol, so only the contract address from official sources identifies the real one.
When should a seller release USDT to a buyer?
Only once the money shows in the bank account itself; screenshots and messages claiming payment are easy to fake.
How can a transfer be followed after sending?
With the transaction hash on a public block explorer, which shows whether it is pending and how many confirmations it has.
Who is paid the network fee on a USDT transfer?
The network, in its own coin: TRX or energy and bandwidth on TRON, BNB for BEP20, ETH gas for ERC20; an exchange may add a withdrawal charge of its own.
What is slippage in a BNB to USDT swap?
The gap between the quoted price and the price actually filled, which can grow on a decentralised exchange when the market moves.
