Who can help me, I have a question, although it is true that I don't know much since I have just started with this..
The price has to reach 0.00075
What does it mean that I paid 6 usdt and the cost is at 0

I am new to this world..what does that mean that is in a circle?

Hello, I am new in this world.
I am starting to trade.
Can someone tell me what this means?
