Money

@Karov has a common saying which I agree with. He states: "Money is Mnemonics". It's a form of memory. Fair enough because in the journal of economic theory a paper by Kocherlakota pretty much makes this exact same statement. Money is really just a means of storing numbers to quantify who owes what. In the memory storage we call money we have the function of "credit" and of "debit". — dana-edwards o18
