Any OG, like @philipma1957, are incredibly advanced for a boomer.
Apart from a few boomers posting here...only 4-6% of people after 64-65 are into bitcoin (I read it somewhere-no source).
I am fine with his diworsification, albeit, disagree that litecoin tech is superior in any sense. Litecoin is a derivative, a copycat..silver to gold, so to speak.

Changing the whole 401K into bitcoin would have been incredible if done 10-11 years ago. I converted only 10% or so of my fiat resources into btc a while back.
Would it have been better if I allocated 30-50%..sure it would be, but as Michael Saylor said: "I could have bought bitcoin at $100 when I [MS} first noticed it, but I bought it at $10000, when I needed it".  Everyone pretty much buys it when they "need" it, either physically or intellectually.

I also understand the @JJG point about buying (or not buying i-bonds). There are/were other, much simpler ways to get interest last year, like money market funds, which are liquid, while i-bonds are not.

I think @philipma1957 is diversified (from what I gathered). Yes, maybe buying i-bonds when btc was at the lows of around $16K was ill-advised, but everyone only know it by now, not back then. Besides, Phil is doing the "work" for many of us (including myself) who is not currently mining, but verbalize about bitcoin.

@philipma1957-what is the Th value/power of your mine, if calculated back to just yourself?
