According to the Hong Kong Wen Wei Po, after mainland investors cash out virtual currencies in Hong Kong, there are restrictions on bringing cash back to the mainland. Customs now stipulates that each person can only carry a maximum of 20,000 yuan in RMB at a time. If a bank transfer is involved, issues such as the source and purpose of funds must be followed in accordance with national compliance and legal policies. A virtual asset exchange store near Tsim Sha Tsui MTR station said that customers need to provide proof of identity whether they are buying or cashing out an amount exceeding 10,000 Hong Kong dollars.
