Aarons presentation on crypto currency had broadened my view on the concept of currency. The idea that there were currencies that were void of control from the bank and government was an idea that had previously been unknown to me. These crypto currencies are virtual currencies that are valued with real money that can be translated and transferred as such. These currencies are virtually non-existent however something such as a single bitcoin is now worth an upward of a thousand american dollars. Crypto currencies are also interesting as it is peer to peer without a middle man such as a bank as well as the fact that it is a set currency base that means that there is no possibility of paying fees or taxes based on the currency aquired. This presentation by Aaron made me want to invest in crypto currencies.
