That is the major problem in my opinion. We need it to make it practical for small transactions as well. There should be less fees in comparison to bank transfer and credit cards for all transactions made through bitcoins. Also, with exchanges charging so much fess like for sending bitcoins and withdrawals , that it becomes a headache for the person receiving bitcoins in his wallet while converting money to fiat. If you are using it as the only payment medium for your services, these fees and extra charges can add up to a good amount.
