The minimum amount for trading is $5. It tells you that if you have a smaller amount, convert it to the currency you want without trading. In this case, you have bought it. If its price increases, your money increases.

I have a problem. Every time I try to trade, buy or sell a currency, it doesn’t tell me that the minimum amount that can be traded is 5USDT. Then, it tells me to transfer the currency, and even if there is a profit, it still makes me lose and I find a loss, knowing that I am a new trader.
