Exchange rate
How many units of the received currency you get per unit of the sent one. The best rate isn't always the best deal: factor in reserve, limits and fees.
In more detail
The best rate in the list is not always the best deal. Factor in the reserve (whether it covers your amount), limits, the network fee and the office's reputation: an abnormally favourable rate is often bait. The rate changes constantly, so check it at the moment and do not delay your order after choosing.
