im not sure how “investment” is defined, but all i want is to preserve some value out of the something of value i’ve managed to save. I could “invest” it in thebank, or in stoks, or in “value” stocks, ot gold, or oil, or whatever i think is most liekly to retain that “value’. I tend to think the best way to preserve value is gold, silver and oil. held for 10, 20, 30, 100 years, gold and silver will definitely hold value. oil, probably. most stocks will be gone. if indeed there is still an exchange.
