Matthew Feeney on How Alternative Currencies Are Gaining in Popularity as the Eurozone Crisis Worsens

For weeks commentators have been discussing the possibility of Greece leaving the eurozone and how a return to the drachma might be facilitated. But when it comes to currency, writes Matthew Feeney, the drachma is not Greece's only option. If Greece does exit the eurozone an alternative currency could emerge or an already existing one, such as bitcoin, could be adopted. In some parts of Greece social entrepreneurship, technology, and skepticism of politicians have already given rise to alternate trading mechanisms and created an environment where cyrptocurrencies could become increasingly popular.
