I have pretty much zero faith in Social Security. And having spent so many years being self-employed with limited income, what I have paid in wouldn't be any kind of sustainable income, anyway.

I have some faith in crypto, and with each passing year a few more "influential" players get involved, thereby reducing the likelihood that everything vanishes in a giant rugpull. I have started slowly stacking some HBD from a small percentage of my liquid rewards. Eventually, the interest will amount to another small income stream... I hope.
