Ok, I will not place any more sell orders before the mining starts but please don't let the price go up to some insane level. Of course there are always people who can not do the math and forget that the price has to go down to (close to) 0 at some time [this is different than in case of other (regular) stocks], but why batten on them.

This is a good idea. I will report the desire to sell shares at some price 48h before I place the order.
