It would be good if a buy-back percentage could be set for every user on a weekly basis. Let's say, 50% of Breadcrumbs a player has, for example, if a player has 100,000 then Holybread will buy 50,000, and if player has 50,000 then Holybread will buy-back 25,000.

These were just examples, price and percentage can be adjusted to different numbers.
