u guys butthurt over someone trying to sell their own skin, why care if it was gifted or not
check steam market average price and put it there, there are alot of dumb rich people who like buying skins the easy way.
And that is where you are wrong. Selling it for its original price in steam market is the worst idea if you need cash.
1- Steam has a fee (guess what, that fee is 20%, you get only 80% of the price as frank said)
2- Even if you sell it, gl passing those money to your paypal or somewhere else, they will be stuck in your steam account forever (unless you decide to lose another 20% of that)
