Baidu’s advertising system is quite similar to that of Google Adwords or Adsense, although it has its own special features. In 2013, it was announced that Baidu began cooperation with Bitcoin. However, Chinese authorities prohibited any means of using cryptocurrency within Chinese territory. Nevertheless, this mandate didn’t stop Baidu from investing in prospective international projects related to the crypto sphere.
