Bitcoin is a digital currency that does not rely on banks, but rather on mathematical algorithms. It can be a powerful tool in microeconomic transactions; it doesn't need any intermediaries, it is not completely anonymous. Unfortunately, the way in which the mainstream media treat Bitcoin is usually for its connection with the sale of illegal goods. It is a neutral instrument par excellence, and it could be an innovative and revolutionary solution in the years to come. The workshop will explain how Bitcoin can be integrated into the blog of a freelance, how the currency market works and the properties of a currency without inflation.
