Welcome to the forum, if you are going to be trading do as said above, use a middleman. Find someone you trust to deal with always run background checks on every user you deem on trading with to make sure they have NO valid/open scam reports or community warnings. Look at users reputation for negative feedback saying "DWC" or other negative feedback that ends up warning you about dealing with the user.
If you have any further questions to ask, please don't hesitate to contact me privately.
Enjoy the site buddy.
