That time to minimize Bitcoin transection fees I told him to send his Bitcoin address so that he can pay me in our local currency when I get paid and I don't need to pay another transection fees because it was little bit higher.
But that is not really true, is it? You used the specified address only once on the forum to apply for signature campaign (8 months after alik111). You never actually sent any funds to that address, so it cannot be the address that alik111 used to buy the coins from you.
Like I said, I am still waiting for any tangible evidence to convince me to remove the negative tag.
