Money is an idea that we all agree on, and nothing more.
Peter Leeds of http://www.pennystocks.net/best-penny... explains that currency has no value besides in terms of concept, and as soon as the system breaks down (meaning that access to money is withheld, or money is taken by the banks) then the perceived value of the money drops.
This is playing out right now in Cyprus, and the contagion could spread to Italy, Turkey, Spain, and Greece.

This Cyprus effect would have a significant and direct effect on you.
1. Precious metals prices could increase.
2. The stock market could fall.
3. The Eurozone could break up.

Any or each of these events could have major impacts on the penny stocks that Peter Leeds discusses. They could hurt some penny stocks, while helping other penny stocks, depending which industry the particular penny stock operates within.
If the eurozone was to break up, it would probably take the form of some nations leaving the Euro while others remain committed to it.
