How much does it cost to send USDT?

Excuse me, could you possibly provide me with some information on the cost of sending USDT? I'm just trying to get a better understanding of the transaction fees involved in cryptocurrency transactions. I've heard that it can vary depending on factors like network congestion and the amount being sent, but I'm not entirely sure. Could you possibly clarify this for me? It would be greatly appreciated if you could give me a general estimate or even an average cost. Thank you so much for your help in this matter.
