I think a lot people get it wrong that you need to keep $75,000 cash in the account and hold it for many months. This is not what Chase wants you to do and they do not even want this kind of customers.
Chase wants to keep your WEALTH at its bank, be cash, stock, mutual funds, ETF, IRA etc. If you get those sitting somewhere that you are paying a fee, such as any of the brokers, or you get an IRA from your previous job, then this is the way to go.
If you keep the cash at Chase and move the $$$ out later, Chase may try to get the URs back.... They want some relationship. It is Sapphire Banking relationship. BA and Wells Fargo both are doing it. Also CitiGold.
