Selling stuff - Quick question (Noob question)

I got one question? For example, I wanna take some HC pve items for boomy and example: 20k gold is 10 coins right? Now for each successful trade I get -1 coin? It's 9. If I have for example 0 coins on my acc? Will I still be able to trade gold on trade?

I meant, will I be able to put on trade 20k gold even if I have no coins on my account available. - And they take away -1 coin after each suc trade. That's all. Or you need to have the minimum of 1 coin to start this trade.

I thank you all! This will help me out a lot.

Yes you can.
