Being able to trade U.S. stocks is actually a privilege for many people. To trade U.S. stocks, you first need to open a USD account at a bank with global operations, so you can deposit funds into a brokerage. The USD you deposit will be subject to the bank's anti-money laundering and tax background checks, and you must be able to explain the source of large sums of money to the bank. If you're a tax resident, the bank and brokerage will also send tax forms to the tax authority in your country. Just the ability to trade U.S. stocks alone can block most people in the crypto space.
