How much should I invest in BTC today?

I’ll be 34 in two months. 140k in my 401k is basically all the retirement money I have. No other accounts other than what my wife has. I see projections right now of BTC at $4M+ per coin by 2050.

So my thinking is right my 401k looks to be worth between 1.5M-2.0M by my earliest retirement age (55). If I were to buy even a half of a bitcoin today, then that could be worth more than my 401k account alone at the end of the same time period.

I haven’t been in the space in a while because I lost a lot of money in it. I bought and sold at the wrong times when I was younger and I got sour to everything. But clearly at this point BTC isn’t going anywhere. It wouldn’t have lasted this long otherwise. So should I just rip out some money and call it being better diversified?

I was thinking of just ripping out 30k of my 401k and going for it. I don’t see the 30k compounded being worth more than 200k at the end of my career. But it could be worth over a million if I parked it in BTC.

Thoughts?
