So you are selling sealed iPhone 6 right its about 450$.
Better you post some pictures along with your name written on paper. Pictures of Phone with all of its accessories if opened , Otherwise The picture of Box etc (receipt too.)
Also if you have any used iPhone let me know i may be interested .
I've got a slight used iPhone 5s I could do for 0.25 BTC.
I'll take pictures of it if 100% needed as its 1:50am and I don't feel like looking for paper
