Stewart Schulze is right. Money is but a social construct based upon trust.

When trust goes out the window so does all value money is supposed to represent.

I just bought a 1922 Billion Mark Reichsbanknote* to remind my kid to understand the difference between true and imaginary value.

Sure, if you understand human psychology, please do play and gain from human stupidity and her predictable greed (Bitcoin, Tesla, Enron, etc) but always remember it is a game and know when to get out.
