You basically nailed it. USD crashed in the 1970s after the Nixon shock, and is basically a shambling corpse losing 3-8% of its value every single year while BTC is 600x the value of a 1913 dollar... and trending up: https://i.imgur.com/PJT01T8.png

Even if they don't give me a raise, I'll still have more purchasing power at the end of a year rather than less as the case with USD.
