0.18 btc for a Full Member is overpriced. Change it to about 0.07 btc. Also, is your post count under 210?! If yes, then you are giving false information or trying to scam without basic knowledge about this forum.
Can you provide any signed message from an old bitcoin address posted that isnt editable?
i saw people buying full members for about 0.125 bitcoin so i dont think he has to sell it for 0.07
