Getting a Hong Kong card is not difficult, but there’s one pitfall you must avoid:

Don't put cryptocurrency money into traditional banks like HSBC or Standard Chartered; it will eventually blow up. These two banks are actually quite useful and are necessary in certain scenarios, so be careful not to misuse them.

Want to collect U? Virtual banks like ZhongAn Bank and MOX can be easily created. A more secure approach is: funds from the crypto world first enter virtual banks, then get transferred to Hong Kong stocks for a round, and the money that comes out is clean. At this point, depositing in HSBC is completely fine.
