Hi,
I was going to fund my waves client with credit card, but I noticed that the approximation is way off what I expected. So I went through all the pages and search forms, but found nothing about the credit card funding fees. The fees should be visible on the same window (card funding window) if you want people to use this feature.
The same applies to the funding with a bank account. You should at minimum have link to the page where fees for funding are described.
Right now both options are suspicious and not very user friendly.
BR,
