Seems that next month 19th National Congress of Communist Party is pushing China to ban everything.
At the beginning of September that started to ban ICO after they started with the exchanges and yesterday they ban Whatsapp. Also, China has begun a 14-month-long crackdown on VPNs and proxy services in the country and made it mandatory for all VPN providers to have a license from the government to use such services
So a total ban for everything that is not under Party's control and seems that this is related to the Congress or at least let's hope that this is related to the Congress and after everything will turn back to normality.
The Congress that take place every 5 years will select the the new leaders of the country. So the hope is that new leaders are more liberal or at least continue the policy priorities as last five year.
