For investors, it is ok to open an account in a bank, but the bank's foreign exchange transactions are different from other foreign exchange transactions, and the bank's foreign exchange transactions have no leverage. For example, the first-hand transaction needs 65,438+10000 yuan, and the external disk can use 65,438+10000 yuan, but the bank transaction needs 65,438+10000 yuan, which is a transaction without margin and leverage.
