<prompt> Human: I just found .022BTC 350 on one of my old hard drives! woot! Thanks to PF I should be able to make a full 5,500 contribution to my Roth this year, but could I substitute some of the for Bitcoin? I know Bitcoin is highly speculative but it would only be 6 of this years contribution. Can I contribute non- to a retirement account?  <response>: You would have to convert it to cash with an existing Roth IRA at most typical custodians.A self-directed IRA has more options for investments.
