I'd say keep your account, I had a crossfire Maj without any items except like two "GP Crates" (Basically GP Rare) guns, nobody ever tried to buy it, but my ltc on crossfire with M4 Spring sold for $750. I loved my major more ^.^
Keep your account, or give it away to a member you trust and know.
Chances are if you give it away as a contest it'll just end up banned and you may regret it.
