As for the deposit, it depends on your needs. This is not mandatory but necessary. For example, after the buyer's guarantee of 3,000 (basic) is activated, there are various weightings. You can also activate 48-hour delivery and 15-day replacement at the same time. If you want to participate in the hot competition, you need to pay 10,000 on top of the buyer's guarantee. If you want the money to be credited quickly, the amount of the money to be credited quickly will be linked to your credit limit and your deposit. There are many specific situations.
