Well the point is that gold's gain of value only covers infoation. But it never loses value so its the best cold storage out there (even tho its better to buy an apartment instead of gold and rent it, it depends on the owner of the money....)
You can also profit from usd/eur etc as you for sure know. But you either gotta invest loads to get some small % or you gotta do it fulltime.
Cryptos get you +100% every year easily, which makes it the best investmdnt out there rn, not even Tesla or Apple get so much +%.
But yeah its all investments :D
