Proxy bidding is the process in which your bids are placed automatically, up to the amount of your maximum bid you set.
Kyoubai automatically does this for you. This allows you to set a higher price early and sit back, allowing you to automatically bid higher than other people who bid as long as nobody else bids more than you. You will proxy bid up to the amount of your current maximum bid.
To make a proxy bid, simply type in a higher value than the minimum bid when bidding on an item. Make sure your proxy bid is not higher than you’re willing to pay, because the price might in fact climb that high.
