The only possible thing long term is gold. Saving FIAT long term is a waste of time
and will actually decrease in value due to inflation.
I doubt that, indeed, the price of gold has increased compared to 10 to 20 years ago, but even then because of inflation. and gold is usually more exposed to costs added by sellers than other investments so the value of gold itself is not exactly what it is. then the storage problem must also be a concern, there are costs that must be incurred for this stor
age matter, whether the storage is handled by us or someone else.
