<prompt> Human: I have 40k saved up in a .50 interest account. I have no loans, no debt, no bills. What is the best way as a young adult to see the money grow? Im wary of stocks after playing around without much success. Could I open a 457 or 401k and deposit what I have, or does that need to come out of my paycheck my job offers both? Maybe even think about opening a small business?Assistant: You could put it in an online savings account that will yield closer to 1. I have an online MMA that yields 0.9. It wont make a world of difference for you though approximately an additional 160yr. I wouldnt venture too far outside of savings accounts, MMAs and CDs though. If youre comfortable locking away the money for at least a year, you could go the I Bonds route too, which will yield a bit more currently 1.18, and has the added benefit of being immune to state and local income tax but not federal.Human: How safe are online bank accounts? I was looking into a few, but most of them seemed new, not much in the way of a history  <response>: As long as its FDIC insured, then its as safe as a brick and mortar bank. Almost everyone that posts in this sub have funds in some combination of Credit Unions, Ally, CapitalOne 360, and brick and mortar banks.
