Ngl this is not going to be approved because about the economy money wise it has always been an issue to keep a lot of cash you are going to lose a lot anyway
If you deposit all your cash in bank when above 5m there is wealth tax
When you buy a property you can only deposit 1m in the safe and you can only have a few like 5 property this will increase when you buy donator stats... but the main idea is only 1m you can store in your house
All of these are to prevent players from just having multiple millions in your account just sitting down because after that point the game just becomes boring to you. You will realize you have nothing to do when you have a lot of cash
That is why the wealth tax is in place taking cash harshly out of your bank depending on the amount it is over 5m
When you keep all your cash in your wallet You Must accept the fact that you can get robbed 30k-50k and to be honest this is nothing if the coming update has the rob limit as 2m then that is a lot worse
That is why you always get a warning that you might face a lot of players pickpocketing you when you get more than 10k cash in your wallet.
So it will always be mentioned again and again
Keeping millions in your wallet is not realistic
Everyone must accept the risk of getting robbed when you have millions in your cash
