It isn’t easy to “park” that much dough, so you will at least have to make some early financial decisions. FDIC only covers up to $250,000 per depositor, per bank, so if you want to park your millions in the bank, you’re gonna need to go to a helluva lot of separate banks.
If you park $700M in Wells Fargo, there is a good chance they won’t go belly up in a few months
