On September 27th, the financial investment newspaper published the article "Hit the ball in the hot spot, the concept of digital currency contains risks." The article points out that although digital currency has become an inevitable trend in the global financial system upgrade, it also helps the central bank to grasp the currency circulation in a timely manner, accurately measure the total amount of money and improve the pertinence, effectiveness and appropriateness of monetary policy formulation.

Secondly, the concept of digital currency and blockchain speculation will not bring substantial performance improvement to the company in the short term.
