Each time any amount of cryptocurrency is sent or exchanged, the currency goes through a blockchain. This process requires a small fee called a ‘network fee’. The network fee is a commission that a blockchain takes from the amount sent in each currency. 

It is critical to make sure that the amount you want to exchange on MedeTrade is enough to cover the exchange fees for both the process of sending your original currency and receiving the new currency you want to buy. If the sent amount is too low to cover the fees of the network, the transaction will not go through and your funds will be lost.
