Bitcoin transaction fees have the purpose to reward the "miners" in return for their services. This is achieved by them solving computational problems and in this way allows them to confirm new transactions and adding new blocks to the blockchain network.
When you make a buy or sell order, the Transaction Fee for the Bitcoin transfers will be automatically calculated for your order and the interface of the order confirmation page, while placing a new order, will show its actual monetary value. This information will also be available in the email receipt you receive when your order has been completed.
Importnat: The Bitcoin Network transaction fees add-up to the total of fees you pay for having your trade processed. Please note that we do not collect transaction fees. Transaction fees are paid to the Bitcoin miners and are determined by demand in the market for transaction confirmation.
