There is only one bid per item. However, if there are 100 of the same item posted, say 10 stacks of 10 memory fragments per stack. Your chance, as a human, camping next to the MP, spamming to try to get one, is pretty much zero every time no matter when you log on to bid on them. Eventually you give up or buy a bot to bid for you. I do not like those two options and I want to see if can beat this bot mechanic, at least, try and see. Here is my suggestion: Now if each bid is with a cool down of, say, three seconds. Does not matter which item you bid, you need 3 seconds to finish a bid state or cool down before the bid is enable again, then a bot cannot spam bid of each of the 100 memory fragment up for sale so a bot to bid on each of the 10 memory fragment of each of the 10 stacks then it will take them 3000 seconds to finish those 100 bids.
