I’m considering not contributing to my 401k anymore and buying BTC

Talk me in or out of it. Im starting a new job that contributes a percent at the end of the year (8-12% depending on company performance) regardless of if I contribute a penny. Why would I put 5-10% of my salary on a 401k and not DCA that same amount into BTC? To me it feels like that money could be better used now where I have access to it even with the tax differences. I just turned 26 and I’m single. Also I have elderly parents who could/should be retired but don’t want to retire because that’s what they like doing so it’s making me question why I need a retirement fund AND actual savings. I live very modestly but I do live in a somewhat pricier city right now and would like to travel (primarily skiing and Europe) while I’m younger.

clarification: Employer is putting a minimum of 8% in my 401k regardless of if I contribute, so no matter what I still have a 401k. The question is basically do I put some in myself or do I use that money elsewhere. I don't get any more money out of my new employer by contributing my own money.
