Bullshit? It's the government currencies that are bullshit. You're replying to someone who lives in a country that actually went through several currencies. They became so worthless they had to be replaced. If you search "Brazil" here on HN you'll find the top post is about how "fake money" saved my country. They essentially tricked everyone into believing this time was going to be different. I'm sorry but I don't believe these people for a second. And neither should you or anyone else.
