Please beware of scams from people you meet in the Pai Ai family. My friend met a person from Hong Kong and a person from Singapore, and they both introduced him to invest in bitcoin on this site. Initially, he invested USD430 and successfully withdrew once, then he nvested USD400 again. And they even helped to increase the amount. Later they claimed that he had too much assets and need to pay taxes to withdraw. And the platform needs to be updated by customer service, and even the App is also provided by customer service. If you have a similar situation, please beware of being scammed.
