I think a fair starting price for each stake is between 0.2-0.5 BTC. The stakes for the waiting list guys will be 0.1 BTC, so a 0.2 BTC starting price seems fair to me.
But fairness doesn't seem to have a clear meaning in this situation.
Fairness relative to what, to buyers or to the devs and community who put a lot of hard work into this?
The call to participation was 1st phase to get in, waiting list is 2nd phase and auction is whole different matter.
With the auction we should aim to prepare for the market and set a real price for the stakes. The call for participation and auction should not be put together and compared because they are different things with different purpose.
Anyway, I would be very interested to hear Utopians view on this matter.
