eBay requires me to bind my credit card in advance if I want to participate in the bidding. If I don't bind my credit card, I cannot participate in the bidding. However, keeping credit card information in the eBay app will increase the risk of being stolen. eBay only replied to me "I received your thoughts"... I hope eBay can restore its past policy, that is, you don’t need to bind a credit card in advance to participate in bidding! ! !
