<prompt> Human: I want to dip my feet in bitcoin investing. I have IRA that has index funds target date. What options are there that would allow me to invest in Bitcoin while still keeping everything within my IRA?  <response>: Theres GBTC, a fund thats traded over the counter and often trades at a huge premium to the actual Bitcoin. Your broker may or may not allow you to buy it.Gambling your retirement on Bitcoin is unwise.
