No, as long as you don't buy gold, his handling fee is to earn the difference. For example, the selling price of paper gold is 295.2, and the income is 294.5. If you buy it, it is 295.2, and if you sell it, it is 294.5, of which 70 cents per gram is taken away by the bank. This seventy cents is a handling fee, no charge.

I hope you understand.
