where i can sell

Where i can sell cs go skins, for real monay? i dont wnana sell on steam

You can use external websites where you can cashout for real money through paypal (I used skinbaron, but they take a % of the price of your skins).
You can also sell them to someone but I don't recommend it since you can get scammed.

you have some sites to sell and open boxes, but to sell i prefer the market community

Try cs.money or facebook groups (yes people still use them).
Reddit trade also helps.
