> Can't really think of any good legitimate use cases for large amounts of cash. Affluent people tend to diversify where they keep their money. They have a few different checking accounts, savings/money-market accounts, brokerage accounts, assets, petty cash, and probably some other things. If you do not have the level of wealth that gives you the flexibility to keep large sums of money in a relatively inaccessible place (e.g. a brokerage account that might take 1-3 days to liquidate and another day to do a bank transfer), you might opt to keep a few thousand in cash in case something happens with your bank, such as your account being frozen or just drained due to fraudulent activity. It’s always prudent to keep reserves in diversified locations.
