Earlier quoted context omitted.
Now apply your idea to dollars, and think about who prints the dollars.
Why do I have to apply the idea to dollars? Nobody is telling me that I will become incredibly rich, without having to put any effort, work or invent anything, if I just buy dollars. Yet the same claim is made about bitcoins, and this is why we must examine whether this claim about bitcoin is true.
There's a lot of disingenuous people out there, that for some reason believe bitcoin or other cryptos are "investments." I guess they missed that they are called crypto-CURRENCIES and not crypto-investments. And then they get upset that they are not, and go on to berate a currency for not being an investment. It's fine to be upset at any swindlers calling a zero-sum or negative-sum game like most crypto an investment, but if you actually read the white papers many cryptos make no such claims.
And there are certainty people telling you that you can get rich off dollars, just look at the FOREX trading peddlers telling you to get rich by trading fiat and leveraging fiat exchanges. I don't attack dollars for that!
And yeah, you can apply your idea to dollars, because one of the biggest way for the government to profit off of dollars is to print more out of thin air, therefore debasing the "investment" of the rest of the dollar holders. You can choose to not apply the idea to dollars, and rather bury your head in the sand if you like, that's your prerogative.
