Transaction fees. Coinbits does not charge transaction fees.
Bitcoin Network fees. When you send bitcoin, Coinbits estimates a fee to cover the Bitcoin Network fee, which is paid to bitcoin miners to process your transaction. This fee will be presented to you before you confirm the transaction.
Exchange rates. Before converting between bitcoin and fiat using Coinbits, you will be presented with a quote for the price of bitcoin. The price is calculated when you initiate the transaction. It is based on the bid and ask prices offered by Coinbits' third-party service providers and includes a margin applied by Coinbits.
