The dollar will keep devaluing long term, not just because of the inflation and the printer go brrr, but also because the most adequate world economies are giving up on it as the reserve currency. Euro, yuan, even the Russian ruble if you feel adventurous, and of course gold.
You should invest all your money in Hexcoin, my brand new crypto-currency that will probably replace all existing currencies within three years, end climate change and cure cancer. It's based on a Blockchain made of AI-generated struggle sessions and unlike bitcoin it is green as all mining is done with carbon neutral energy generated by green clean organic locally sourced artisanal coal (and a slight amount of baby seal bludgeoning).
