As long as you meet the conditions for opening an account, have civil capacity and have an ID card and a bank card, you can open an account in a futures company. Choosing a brand futures company with good service and high quality will ensure your operation. After all, if one day a small futures company is swallowed up by other companies, you will have to transfer your account and be forced to close your position.
Of course, securities companies can only use their ID numbers to open accounts in securities companies. Unlike futures companies, it is arbitrary.
