if the market price is 0.3 ,the auction price here is more than 0.31, then what would you do ? I am sure most guys will buy it directly on markets even he didn't cancel his bid.
IF I obey the rule strongly, Then I will just let the my bid here let it be , and wish I would be kicked out, it's a smart choice.
but what if I am not kicked out finally, I am sure I just have no more BTCs to buy there shares even I really want to pay them to obey the rule.
Also, I know reputation is really important for the bitcoiner , but I think it's not just simply about "obey the rule".
whatever, cancel my bid is the best choice both for the seller and buyer. If people stick to say " you should obey the rule,anyway" , then I say sorry for that... In this situation , I just don't know "what's the right thing to do" , also it's maybe one of the problems of 7 days period of auction....
