All right, gentlemen, let's all calm down ourselves.
The purpose of this, or indeed any other auction is to establish a fair price on the lot in question, NOT allow the fastest bidder to take it all. Moreover, in one of my previous posts in this thread I have explained that we are trying to weed out profiteering and speculation and only allow the joining of big investors who see potential in the XDN and its Foundation. Besides, if we'll keep making multiple bids with decimal increments, the thread can very well come under attention of the moderators and get closed because of spamming.
That is why I believe 1 satoshi is a fair and reasonable minimum increment.
