According to the news of Sanqin.com, on October 31, Professor Guo Jianqiong, professor of Xi'an Jiaotong University, vice president of Xi'an Urban Block Chain Technology Application Association and chief economic adviser, published the article “Cold Thinking” under the blockchain “hot”. The article pointed out that the favorable policy will only be transmitted to the blockchain concept stocks and a few mainstream cryptocurrencies. Whether it can be continued depends mainly on the application, and the industry policy has a complete set of logic. China's blockchain industry started early, and talents are sufficient. It is equivalent to taking a step ahead of other countries. However, the current industry is mixed. How to correctly use blockchain technology is a big challenge, otherwise it will repeat the mistakes of P2P. The blockchain industry will not become a regulatory object, but will become a regulatory tooth and a new governance tool.
