Is there something wrong with the bank account with interest?
The one, that you create at the bank itself, Downtown.
I've made an account with 5000$
And what now?
Neither can I add more, nor withdraw any.
Do I have to wait for a specific time?
You can manage your prepaid card (deposit or withdrawn) using the ATM in any "Breeze store".
(IMHO having to micromanage money from/to bank/prepaid-card and cash is another useless form of grinding... but that's the way it is...)
