That’s strange because I see it essentially in reverse of that:

To change the Bitcoin price, vote with your dollars, going long or shorting. You will materially impact the order book and resulting price. Other ways exist: starting a company like the ones mentioned in the article.

In contrast, in federal elections you have a vanishingly small chance of casting a deciding vote between two participants in an actual oligopoly (more specifically, a duopoly), who are themselves primarily allied with powerful interests which include the banking sector. Does anyone really believe their reps are responsive to them on issues like monetary policy?
