I'm not a crook, I've never tried to steal your stuff. buying them for money, I do not know who is on the other side of the screen. I just collect and use the exchange to collect top things. I'll give you a tip: use steam guard, do not click on unknown links, use only verified sites for sharing and check the address bar, do a virus scan of your software, change the password in the steam at least once every 3 months. good luck!
