➡️What is the purpose of the timer displayed with the ROB-BOX?

When you have a Rob-box during a Street-mission it is placed in the slot box of the OYABUN game, it will then be displayed with a timer

The higher the box level is, the longer the time is

The cost of openingthe Rob-box (in OYAB) is linked to the timer. The closer to get to 0, the lower the cost.

Once the timer is at 0, the cost of opening the box (in OYAB) is at it' s lowest. It will remain there until the box is opened.

The opening cost (in OYAB) depends on the level of the box
