You can earn a couple of Bread every day by doing daily tasks. Click on your profile picture and the on the button on the top that says "earn bread" there you can see the daily tasks and once they are completed you can claim bread. You can also delegate SP and earn Bread in return.

Thank you. Now I see it. I currently have "Finish 5 quests", "Win 3 arena fights" and "Buy 1 item from the item store". All of these daily tasks will give 1 Bread for completion. This is the first time I notice/see this page.
