Writing at the Tampa Bay Times, University of South Florida professor Murad Antia writes that he has little trust in crypto-currency. A snippet; follow the link for the full explanation of his reasoning.
So why do some people believe in cryptocurrencies? Why invent a currency outside the purview of the government and the Federal Reserve Bank? It is a horrible idea. There needs to be a central control of the money supply to prevent and control speculative excesses. It is reminiscent of the shadow banking system collapsing during the 2008 financial crisis, which worsened the economic downturn.
