With the current economy, silver and gold are bound to continue upwards. People who say that gold is being manipulated and inflated by big money in America are wrong. Gold is being bought by the major countries who have huge reserves of US dollars, and they understand that the US reserve will inevitably get flushed down the shit hole if this country doesn't change direction soon, and it won't change direction soon. Humans are procrastinators by nature, so for us to see a fix, this fix will probably occur after a breaking.
Let the train ride, because paper isn't worth shit.
Anything that can be exponentially created (paper money), will always face pitfalls if used as a currency through human manipulation. Look at our current levels of inflation... if you wan't to argue against this, you're simply ignorant. Anything that has logarithmic growth in regards to being "created" is the ideal substance for a currency, such as metals because it cannot be manipulated by humans.
Humans will always cause issues with anything that they can control, dictate, manipulate, or govern. Humans can't do this with mother nature (right now).
