What your rate shows

What it shows when I enter my account. It's also how much I can get on my card.

Isn't this misleading?
It isn't. This difference you see is normal. On Wirex, there are two exchange rates: One for buying bitcoins and one for loading the card. The "Buying Bitcoin" rate is higher than one for Loading Bitcoins. But other than that, What you see is what you get. There are no fees for loading your card or Buying Bitcoins in Wirex / E-Coin.
