But if they did, they would see that you do not need a WalletBit account to pay a merchant though WalletBit, that's the beauty of it. Simply click on "Don't have a WalletBit account?" and a QR code will be presented for you to scan. Bitcoin is to WalletBit what WalletBit is to bitcoin in my mind.
I changed the buttons to say Bitcoin, in fact I think it looks pretty good.
Actually this was what originally confused me (I had no idea that I could pay *without* having a Walletbit account) so am glad you have changed that and made it more obvious that you can pay with a normal wallet (not wanting to hurt your business but we are all in the Bitcoin business after all).
