How to trade here?

First step: learn everything you can about how to avoid being scammed.

This isn't a CD key trading site, its a giveaway site. My suggestion is if you want to do trades instead is to go to a trading site.
Edit Whoops I'm a fool I suppose. Just not something I used.

Remember to always check to make sure that the person you're dealing with really is who they say they are. You can easily change your steam name & avatar, so don't believe someone who just claims to be whatever big name trader they say they are.

since you have 0p, everyone will ask you to go first with keys.
trade with users with high rep, and ALWAYS check you ae trading with them, not with an impersonator.

install enhanced steam (works better on chrome) to cross-check their profiles. usually scammers add you when they see you make an offer in a thread.

Start trading for small games first. Never, just never go for big games in your first trades, even a high rep user could scam you.

Try to use both barter.vg and steamgift to trade. List what you have and what you want to start it off. Do trade with reputable traders first and 'go first' to build up your reputation slowly. Trade non valuable stuff in the beginning so in case you got scammed, it wont hurt that much.

• Always check their other trade topics to see how they have behaved toward others before you want to leave your suggestion in their threads or if you want to reply to their suggestion.

It also works when someone randomly added you on steam and asked you for trade.In this situation, you must ask him/her to give you link to his/her Steamgifts profile and then check it to get sure it actually lead you to his/her Steam profile.

• Never hurry to trade. Always there's someone else for a trade.
