How do people make so much money?

[Kip]

Trading.

1) You play normally till you hit about 3-4m, then buy up some high tier item and sell it for more. As you trade more, the more people you add on steam = the more contacts you have = more offers you get.

2) Be an annoying person to people on steam, be semi-aggressive in your trading, bend words to your favour, tell white lies here and there, this is the trading world. If the other person is smart, they wont fall for it, meaning you've just gotta do normal trading with them as they also know what they are doing.

...

Consequences conveniently left out:
You may become viewed by some as annoying, manipulative, and dishonest which will damage your reputation with the community, result in fewer contacts, fewer offers, and fewer chances at earning all that gold you wanted in the first place.  Proceed with this strategy at your own risk.
