Yea, I think it's something you've got to somewhat enjoy doing.
I tried doing CSGO trading, but I couldn't be fucked. There aren't really any good sites for it, and there are way too many scammers trying to steal stuff from you.
Runescape trading is ok, but I don't like how the prices of items change so fast. It's very inconsistent. Toribash is my favorite place to buy/sell stuff.
Plus there's a well organized system of being able to communicate with others.
