the calculations are not meaningless, because nobody in the world will spend let's say 100$/month on eletricity and then sell you the coins for 10$
you can spend 100$ or 1000$/month on eletricity, but then for example, no one wants to buy your coins
have you thought about this version?
Hello.
I risk to express myself badly in English.
In my opinion a good starting price is a price that pays electricity costs needed for mining, calculated at the first trading day. That's why I say 1 $ for 1500 EDL. Obviously everything can happen, I hope not less
. If it will be less I will stop mining in few days, I will change money. If will be 1 $ for 150000 I will not even sell those mined 
.
