Let's say all your assets were collected and you only had two options: You could either put them in US dollars or Bitcoins forever. You will never able to save it in another currency again. What do you choose?
If I'm poor, I chose USD. Because short term will prevail, since everything will be spent in a few weeks anyway.
If I'm wealthy, I chose BTC. Because in a few years dollars will worth almost nothing.
PS. I voted BTC
