I don't use Minibits wallet. But I do use Primal that is tied to your nsec and Strike that is tied to your ID Card.

I would consider in your case to use the Strike App. You can download it from where you are and it will give you additional benefits. I have a recurring weekly saving setup and I pay no fees by doing that. If you want I can further explain how easy is to move sats from Primal to Strike and vice versa. Send me a message.
