There's only one way of the US dollar value and it is DOWN.The fiat money printing monopoly creates only inflation and ruins the value of people's savings.The dollar value doesn't increase,the other currencies decrease in value faster than USD.
I think it's more so that people ruin their own savings by not allocating a portion of it to different (more promising) assets. Everyone by now knows that fiat only loses purchasing power, but not everyone hedges against it.
I'm not sure if it's mainly ignorance or just the average people being very risk averse, but it's quite shocking how they let it happen and watch their savings (they worked their entire life for) depreciate a percentage or two annually.
Bitcoin has gone up so much throughout the years, that it has undone every lost percentage in purchasing with just its first bull run years ago, and when you add the bull runs that came after that it's even more impressive.
Buy Bitcoin short central banks. Pretty much that.
