The amount to be received in the auto conversion is an estimate. This is because the conversion fee used at the time of the auto conversion may not be the same fee in effect when the conversion is actually processed. This fee is directly linked to your level in the Nomad Pass program, and your level may change between the time the auto conversion is scheduled and its completion.
If there is any change in your Nomad Pass level, the conversion fee will be adjusted, and, consequently, the final amount will be updated to reflect this change.
