If you have a 401k I don’t think you could.

I didn't discover Bitcoin until about 3 years ago, and didn't fully get it until LUNA stole from me. This leaves me about 5 months to go before I can withdraw penalty-free my own money. Taking the penalty now doesn't make me any less of a Bitcoiner. Just means I have less to buy Bitcoin with.
And, of course, when all of my 401k's were started and growing, Bitcoin was but a collection of Cypherpunk ideas that had not yet been rolled into the perfect recipe that we have now.
I haven't contributed to a 401k in 20 years, as I had my own company for the last 20. Still, having them doesn't make me any less of a Bitcoiner.
Of course it doesn’t. I’m came to realize that 401k and IRA’s are nothing but a scam and a psy-op on the American public to keep them invested in the corrupt and manipulated economy we have right now.
