A fixed exchange is an exchange performed at the same rate, which is displayed to you at the beginning of an exchange, regardless of subsequent rate fluctuations.
A floating exchange means each transaction may have its own unique exchange rate because of rate fluctuations, market conditions, and network fees. The rate might change at any moment; as a result, you might receive more or less than you thought you would.
During a fixed exchange, Breet lays down a small reserve to guarantee your safety from exchange rate fluctuations. It's included in the rate you will see at the beginning of the exchange, with no other fees included. Because of the rate risks we take, the fixed rate may be lower than the floating exchange rate. However, it gives our customers confidence in the amount they will receive.
