What is the difference between Place an order and Quick transaction?
If you want to buy digital currency immediately - select the Quick transaction option. Then you only indicate the amount you want to spend on it, and the system automatically uses the best of the offers (at the lowest exchange rate) and exchanges funds for the digital currency you indicated.
- post only - offer post only is to ensure that you always pay the MAKER commission. When you try to set up this type of offer, you can be sure that it will be issued to the list of offers (orderbook) or canceled (in case of immediate transaction, which would result in collecting the TAKER commission)
