Subtract the fee, then calculate the BTC amount

Does all 100 USDT buy crypto?

This example uses 100 USDT as total spend. A 0.1% fee is 0.10 USDT, leaving 99.90 USDT to buy BTC. Real platforms may use different fee currencies, discounts and calculations.

How much BTC is received?

At an example Bitcoin price of 50,000 USDT, 99.90 ÷ 50,000 = 0.001998 BTC. Here, enough Bitcoin is available at one price. A real order may fill in several parts at different prices. The difference from the price you expected is called slippage.

What should you review?

Check the asset, total spend, fee and expected quantity. On a real platform, also verify eligibility, order type and the current price. This site does not provide live prices or investment advice.
