Due to the nature of cryptocurrencies and their fluctuating network fees, the exchange rates across all product offerings is subject to change as the network dictates. As cryptocurrency markets are always open and experience no “down time”, each asset is constantly changing based on the network’s activity in real time.
This in turn affects all exchange rates on the platform. As the prices are updated in real time, this will also have an affect on the exchange rates when using the Swap feature. When you confirm a Swap order the prices are locked in at that current price.
