Sure, the dollar is worth just 2% today of what it was worth 100 years ago; 10% of what it was when I was born, and 68% of what it was worth 40 years ago (which assuming I live to 100 is how much longer I have).

Still, I don't keep my money (for the most part) in nominal dollars. I keep it invested in real estate and stock mutual funds (i.e., shares in US and international companies).

Over the long haul those have held up quite nicely despite inflation. And that long-term track record of over 150 years is quite comforting for me...

As for tech stocks, I don't try to pick individual ones - I invest through smart investment managers who have been doing this professionally for decades. Between diversifying across sectors and multiple companies' stocks, my risk/reward ratio is more than adequate.

I certainly wouldn't claim to be expert in crypto. I understand the blockchain technology underlying it to an extent, but that's about it. Is it possible that if I knew a heck of a lot more I'd invest in it, maybe. Though I've read articles written by people who have studied and understand it a lot more than I do, and they seem singularly unconvinced.

Finally, I'm happy you feel comfortable with putting your money in BTC and others, and for your sake, I hope they don't collapse while you're invested in them.
