Usually those people who have that huge amount of money do not literally store all of it in their home's safe. They store it on banks for time deposits, insurances, investments, and other profitable way. Plus, people who have those huge amount of money do not use a physical money, they pay their bills with cards. Hassle free right? I think they had only little money inside their wallets.
From what I've seen they store it in savings since hackers can't access savings with CC and DC dumps. I think some banks allow withdraws from network ATMs from savings, but it has the 24-hour limit. Withdrawing tens of thousands requires FBI paper-work in the US I believe.
This thread turned out about how I expected. No real answers or examples.
