What is Dutch one-dollar auction?

For our novice sellers, their reputation is low and their popularity is low. In order to improve their popularity, although most of them lose money, they will not lose much. In Dutch auction, the number of released treasures is multiple pieces. When preparing to release one yuan, if the number of treasures is released in multiple pieces, it will be automatically transferred to Dutch auction. The rules of Dutch auction are: the highest bidder gets the treasures first, the bidder with the same price gets them first, and the transaction price is the amount of the lowest successful bid. Therefore, the winning bidder pays the same price for each treasure, that is, the amount of the lowest successful bid. The higher bidder gets the required number of treasures first, and the last winner.
