A virtual asset exchange store in Tsim Sha Tsui, Hong Kong, is thriving, with most customers coming from mainland China. Cash can be exchanged for USDT, or vice versa, and digital currency can be exchanged for Hong Kong dollars or US dollars. However, for transactions over ten thousand Hong Kong dollars, an ID must be presented.

Hong Kong's approach to virtual currency is relatively relaxed, attracting many mainland customers. However, USDT cannot be traded on formal exchanges; it must first be exchanged for Bitcoin, Ethereum, etc., before further transactions. It's somewhat like taking a detour to buy groceries; it takes a bit of effort, but you can always get what you need.

When cashing out from Hong Kong back to mainland China, the cash limit is twenty thousand RMB. If it's a bank transfer, the source and purpose of the funds must be clarified and must comply with regulations. This is similar to buying a large item abroad and having it sent home; you must declare it and pay taxes, and you can't do it secretly.

Therefore, while virtual currency trading in Hong Kong seems free, there are actually hidden rules. The regulations are set, and if you want to play, you have to follow the rules. This is not a game.
