We can define ICO as an initial coin offering. Which means that a person will offer the investors some units of new cryptocurrency. It can also be a crypto-token which they give in exchange against cryptocurrencies like bitcoin or Ethereum etc. The first and initial token sale was done by mastercoin in July 2013.
