Just a thought to increase Burying Treasure and Treasure Hunting....
Treasure that you bury collects interest from the game.
To gain interest, the treasure must be buried for X consecutive days.
Interest rate is an Annual Percentage Rate (APR) of X% calculated daily.
Successful treasure hunts prevents interest collection for X days.
Daily Interest Amount = (Buried Treasury at Location * APR) / 365
