So I'm sure that majority of pimd players do not use the atm part of the game. But what if one day you were playing pimd just like any other day and you accidentally clicked the ATM and to your surprise, found 20Bil on the bank even though you're completely sure there was nothing in there at all? What would you do? No this did not happen to me, just a random thought
I would keep it in the bank for a rainy day. What if i get in trouble someday and all my money and tuts get taken? 20b would be a reasonable amount of money to have enough for max plunder. Maybe id add in 2-3b also.
I'd keep it there till I really need it and besides it magically was there so who knows more might show up magically
