<prompt> Human: Pretty much title. I want to take control of my 401k and invest a portion of it into some crypto-currencies. I do not want to withdraw anything, just to convert some of the investments to something like bitcoin. I am a complete novice at this, so please ELI5.Edit: Almost all of the posts are about how its a bad idea. I just wanted to get advice on how to do it the best way, not about why I shouldnt. I do not need to invest for decades, just one large investment for a year at even a 10th of the current returns would set me up for a very long time. And losing my entire investment would not hurt me much at all, as I am very young and make great money now with a very promising career path.If someone had posted this same thing a year ago, itd have gotten the same exact its a bubble, stupid responses, but look whats happened this year alone.  <response>: You can only invest in your companies 401k options, so you cant.Even an after tax account, the major brokerage firms cant touch crypto. The SEC rejected a crytpo etf fund a few months ago because their isnt any regulation or monitoring of insider trading, money laundering, and pumping.
