Bitcoin is rapidly becoming part of the everyday lexicon. Following David Woo's investigation, National Australia Bank's Emma Lawson looks at its creation, use, and quality as "currency," and find that Bitcoin meets most, but not all the conditions required to be a currency. Lawson concludes Bitcoin may not be the most efficient monetary system, given the costs to create, and that the supply set-up can be seen as both an advantage (hyperinflation is not possible) but also a disadvantage (there are conditions which may create deflation). But, if enough people believe in it, and use it, it may be here to stay as a payment system. Simply put, its success (or failure) will depend on establishing trust and adoption.
