How difficult is it to speculate on U.S. stocks domestically?

First, you need a Hong Kong card, which must be obtained in Hong Kong.
Second, all brokerage apps that allow trading U.S. stocks have been removed from app stores.
You need to switch to the Hong Kong store or download from other regions.
Domestic banks only have an annual foreign exchange quota of $50k USD.
You can only transfer $10k USD per day, and $50k USD per month.
This means it takes at least half a year to transfer the full $50k USD.
Moving money like ants is even worse; family members transferring twice into the same account
will trigger bank risk control, leading to frozen cards.
The threshold for playing with funds on securities platforms and Hong Kong cards is really high.
Some people talk confidently without any trouble, but I just managed to move a few tens of thousands in these past few days...
