I'm actually 40 and I was never into 60/40 portfolio. To me the "40" sucked. It was something my father, who was in his 70s, was holding when I was making my first steps in "investments" (which in other words meant I had enough money to start thinking about it).
Out of all my friends nobody had any bonds. The prime thing to own if you had funds was real estate and for those with less liquidity either collectibles or stocks (usually tech). 10 years later I still don't own any bonds. My portfolio is 70% bitcoin 20% real estate 10% fiat, although numbers can change rapidly. If we go to $100k the value of it will exceed 90% bitcoin.
