Gold

I rise to speak on the concept of competing currencies. Currency, or money, is what allows civilization to flourish. In the absence of money, barter is the name of the game; if the farmer needs shoes, he must trade his eggs and milk to the cobbler and hope that the cobbler needs eggs and milk. Money makes the transaction process far easier. Rather than having to search for someone with reciprocal wants, the farmer can exchange his milk and eggs for an agreed-upon medium of exchange with which he can then purchase shoes.

This medium of exchange should satisfy certain properties: it should be durable, that is to say, it does not wear out easily; it should be portable, that is, easily carried; it should be divisible into units usable for every-day transactions; it should be recognizable and uniform, so that one unit of money has the same properties as every other unit; it should be scarce, in the economic sense, so that the extant supply does not satisfy the wants of everyone demanding it; it should be stable, so that the value of its purchasing power does not fluctuate wildly; and it should be reproducible, so that enough units of money can be created to satisfy the needs of exchange.
