Tips for people wanting some free money to spend on cheap games: Since CS2 (Counterstrike 2) started with the new case system, the prices on different cases can be sold for a higher amount of money than before. This means that if you play for a couple of hours (depending on how many kills you get) you'll get enough XP ( 5K XP) for the weekly case drop which includes different types of cases and also emote/weapon skin. Normally you'll get around 1.5USD for the crates, but if you are very lucky you might get a really good case or weapon skin that will net you some good money. Keep in mind you can only get one case drop per
weekly reset [here you can find the time before the next reset].
Another tip is to get rid of the majority of your Steam trading cards, the ones you get from playing games. While it does not seem like much at first glance, when you start selling them, you might be surprised to see you have earned a few bucks from doing so. PS: If you suddenly can't see the prices on the cards you are selling, it is just because you have clicked too fast through them or you have listed a large amount in a short time, which will make Valve hide the prices until it has been a few hours. You still can find the prices on the market, so not really a big deal, but I thought I'd let you guys know.
I do this from time to time and I like to think of it as a fun game to squeeze some extra free money from the hours I play games, instead of opening the wallet too much.
