I received the same pop up and was expecting to see a thread about it soon. I was surprised to see that they are FDIC insured for over a million dollars. That is far more than what is standard, isn’t it?
My AMEX savings account earns around 2.1%. Granted, my huge emergency fund (a years worth of spending) stupidly sits in my low earnings Wells Fargo account.. I don’t know why, but it’s nice having it “right” there, as opposed to the few day delay transferring money between accounts.
