Odaily Planet Daily News According to Hong Kong Wen Wei Po, after mainland investors cash out virtual currency in Hong Kong, there are restrictions on bringing cash back to the mainland. The customs now stipulate that each person can carry a maximum of 20,000 yuan per trip. If bank transfers are involved, there are issues related to the source and use of funds, and national compliance and legal policies must be followed. A virtual asset exchange store near Tsim Sha Tsui MTR station stated that customers, whether buying or cashing out, must provide identification if the amount exceeds 10,000 Hong Kong dollars.
