It would be fine... I've used dozens of random online banks, following the incentives and interest rates. As long as you do the due diligence to make sure it's not a scam, they're all the same. FDIC insured is FDIC insured
That is a real worry. I always make sure to keep my accounts below $250k. But with so many banks being so similar, it's not hard to diversify a bit.My real worry is I have over the FDIC amount insured in my Credit Union bank. and need to move a little money to stay safe
