So, just answering questions with questions then? Like my point becomes worthless because you watched a youtube video on the blockchain once? You still have to define “real currency” before you can call something “fake currency.” If people perceive something to have value, then it has value as a currency. Something is only worthless if no one perceives it to have value. Crypto isn’t any more “fake” as a currency than gold or the dollar. Both also only have value because people perceive it to. The only currency that has permanent value is something that produces something completely necessary to human life. Livestock and seeds will always have value as currencies. Obviously the value decreases when there’s an abundance, like anything else, but little else in the world has “real” or “permanent” value.
