In order to sell us coins to FIFA 18, you need to choose platform on which you have coins, and type quantity which you want to sell. To be able to sell us coins, you need to have transfer market activated on your WebApp application.
WARNING: It's important how much coins do you have on your account, not how much coins do you have in general. Pricing for each account is seperate, same as amount in "Guaranteed amount of money if account will be banned during coins transfer" is seperate from each account send to us.
To sell us coins, we need to ask to give us access to your WebApp account. We do not ask for e-mail password, so we can't change any of your account passwords.
