Agreed. But it will be many years before the dollar reaches 0, if it ever does.
0 is too pessimistic of a prognosis. But the purchasing power of the USD today is 40-50% weaker than what it used to be 30 years ago. If we go back further into the past, we are probably looking at 80 or more percent. At the same time, bitcoin has appreciated tens of thousands of percent since it got listed. Maybe even more, I never looked this up.
These people have more than enough of their basic needs covered and can afford a very high level of consumption, investing the rest. Their case is very different from the beginner approaching this section.
Very true. But at the same time, no one needs to follow anyone in numbers. The $50 million they invest can be the $50 you invest if that's all you can afford or are willing to invest.
