Be very wary of those online banks. Yes, FDIC insured, but expect to be driven to wits end by poor customer service (India), or essentially no customer service when they put your account in “difficult customer” status. Horror stories abound of locked funds, funds “lost” in transit that take months to recover, accounts that in actuality pay less than the advertised rate (they “accidentally” out your deposit in wrong account type), and so on. Read customer comments before moving and funds in!
Not just Bask, they’re all bad.

However, I do use Marcus Goldman Sachs savings online and so far, it’s been trouble-free. Just got a text seconds ago saying they raised my interest rate to 3.90%. I will forego a little higher interest to keep my sanity (and my money).
