Fixed or floating rate: which to choose
What each rate type promises, what it costs, and when one is better than the other.
Fixed rate
The amount you see is the amount you get. The rate is locked when you create the swap, and as long as your coins arrive within the time shown on the swap page, the market can move as it likes without changing your result.
Choose it when you need a predictable amount: paying someone, topping up a balance to an exact figure, or swapping during a volatile market.
Floating rate
The final amount is set by the rate at the moment your coins arrive. If the market moves in your favour while the network confirms your transfer, you get more; if it moves against you, you get less.
Choose it when the exact figure matters less than the current market price, or when your transfer may take longer than the fixed-rate window.
What if my transfer is late?
A fixed rate only holds for the window shown on the swap page. If your coins arrive after it, the swap goes through at the rate at arrival, and the swap page shows the new amount before anything is sent.
