Ok, here's my opinion about this bank script.
This may be an unpopular idea but it seems to be the truth. To convince every player to use this function, there's a need for players to lose money upon death, a tiny percentage will do which is between 5% to 10%. Else, everyone will just keep their money in their inventory without storing it.
Hold your horses about the bank interest players can gain monthly, I know that it is mentioned too. However, this will cause every player to liquidate - which is to sell off - their properties, vehicles etc so as to store the maximum amount of money in the bank to gain those interest. As a result, businesses and properties become empty and not owned. Worse still, players may only log in once a month just to collect their monthly bank interest.
In conclusion, supported for the storage of money in bank only if the mentioned script change is implemented but unsupported for the bank interest.
