Since the regulatory rules of digital currency in various countries and regions are inconsistent, traders of digital currency must clearly understand whether the holding and trading of digital currency comply with local laws and regulations. In order to avoid the loss caused by the money laundering of criminal suspects as much as possible, we need to have legal qualifications in the local area for all access companies, be regulated by the local government, and comply with anti-money laundering regulations, and treat every user. Implement strict KYC verification. If the information is found to be untrue, we will be held responsible.
