For newly added cards (including replacement cards received from your bank), you will have a temporary limit that allows you to add a certain amount of money per 24 hours. Some users may find they have a lower daily limit to begin with, however, your daily deposit limits will increase over time and we can't change these manually for you. Try and top up your desired amount. If you wish to add more than your daily limit, you can add money by bank transfer.
Other than that, there aren't any specific limits. On some occasions, we may ask you to verify your source of funds, which is something we need to do to meet our regulations.
