No one is going to pay $20k of REAL money for bitcoins
Right, but many people will pay $20k of the "money" issued by the Federal Reserve.
I suppose it depends on your definition of "right wing". Pretending that there is some sort of progressive spectrum from say the GOP to Libertarian to this is ridiculous. Most in the US tend to Define Right and Left as how much Freedom is protected or Regulation is imposed. Neo-Nazism is about hateful oppression of minorities. That data point has no place on this spectrum. Now this article is, of course, about Germany. I really don't have direct experience with politics there or what the general idea about what is right and left there, but being strongly US leaning website, you can understand the reaction to TFS using "far-right". Calling it left-wing is equally as ridiculous.
Playing the game of trying discredit and put a label on a world view you don't agree with on a movement few can stomach is just childish. Stop legitimizing their hate buy saying its just a few degrees away from a position a very large amount of people hold.
Fast, cheap, good: pick two.
