mainland investors who cash out virtual currencies in Hong Kong face restrictions when bringing the cash back to the mainland. Customs regulations now limit each person to carrying no more than RMB 20,000 at a time. If the funds are transferred through a bank, issues related to the source and purpose of the funds must be addressed in compliance with national policies. A virtual asset exchange shop near Tsim Sha Tsui MTR station stated that customers must provide identification for transactions exceeding HKD 10,000, whether buying or cashing out.
