We are the general agent of Xihanzhi Gold in Jiangsu. You are talking about electronic disk operation. Are you sure you want to pay 20% of the gold price as a down payment? You can operate without paying the full amount. 24-hour trading. T+0 mode. You can buy and sell at any time. If you want to get the real thing, you only need to pay 20% in advance and the rest will be paid the next day. But only 10 ounce. Less than 10 ounce must be paid in one lump sum.
