Assume you are advising a very wealthy individual (about $500 million invested, all in $US). She has seen the escalating growth of Bitcoin's price and is considering investing $50 million in Bitcoin or one of the proposed alternatives (in particular, the DDP project of the Federal Reserve). She has a preference for Bitcoin since she believes that each country's central bank strives to maintain its currency at some target level, and thus currencies such as the US$ will always be subject to actions of the Federal Reserve and other government agencies (e.g., to stimulate trade and to control interest rates/inflation). In your initial post of between 250 and 500 words, draft a brief recommendation to her commenting on the suitability of Bitcoin versus other possible digital currency alternatives as an investment. In your discussion, comment on the issue of whether or not the Fed should be concerned about the increasing importance of Bitcoin and related (non-currency) alternatives, for example, because of issues relating to money supply or the possibility of illegal transactions.
