In this segment of The Motley Fool's all-financials show Where the Money Is, Fool financial analysts Matt Koppenheffer and David Hanson take a question from a Fool reader on Facebook who writes, "Are online banks a good place for keeping emergency funds? Or is keeping it in a bank savings account or checking account better?"

The guys discuss why entirely online branchless banks like Bank of Internet (AX 2.09%) or Capital One 360 (COF 0.66%) make perfectly safe and sound alternatives to traditional banks and the importance of liquidity when planning an emergency fund.
