At 23:53:07 WhalingWhales bids .16 BTC. At 0:52:47 Monetizer asks if he can bid .18 BTC, I would assume this would be a bid of .18 BTC.
At 0:53:15 the OP offers a buy it now offer for .2 BTC, and at 0:54:29 Monetizer accepts the buy it now offer. I would say that Monetizer should be the winner as he was the first to accept the buy it now offer
Did you miss my 0.18 at 12:51.57?
I did not, however you quoted the message shortly thereafter with a changed amount of .16 btc and I would personally interpret that as you saying that you bid the higher amount by mistake. If I were the OP I would have clarified much earlier then when the bid would have expired
