What's the most money you can have in a checking account?

Question

(Speaking of the lottery) How much can you put in a regular checking account?

Answer 1

The amount equivalent to five days of my living expenses, say 500 pounds.

Answer 2

you can have as much money as you want in your checking account, but bank and credit union accounts are only insured by the federal government for a maximum of $100,000.

therefore, I would make sure I have less than that in each account I held.
