How to make wallet credit (aka steam money) on steam?

It used to be easy to make money with steam game trading. Now, it's really hard that it even made me to stop trading. :'(
Now, the only way to make some money is by trading steam keys (preferrably by selling them on G2A, Kinguin, etc.) or by trading cards (but you need to have a loooooooooooooooooot of accounts in order to actually get profit by them).

get some games that drop cards, preferably during sales... play games/farm cards by being idle... profit.
or get the most games you can get on massive giveaways and then sell the cards of the ones that have cards.
or yet, selling event cards.
or yet, playing games that give drops, like CSGO, TF2, Don't Starve Together, etc and put all your marketable items in the market...
linking your acc to a Twitch acc and watching the CSGO/Dota league games for the eventual drops of boxes/in game items they make for people watching the league games... (to get the ones on the CSGO league you need to have CSGO)
basically: spending some money or time to get games, play, sell marketable stuff...
could also try some buy low, sell high on market, but that might be more time consuming, and you need to take in account Steam tax cut.

• Make roughly 7000 crappy icons in MS Paint
• Write a blank HTML page with a big button that reads "UNLOCK ALL ACHIEVEMENTS"
• Package the two and sell that as a game

Advanced techniques for more moneymaking:

• Add cards made with pics taken from Google
• Add stock 3D items, call them in-game collectibles and make them sellable on the Steam Market
• Repeat the operation while changing your name as a "developer"

buy cheap bundles, idle games, sell all their cards.
create badges of easy to get card games, level up steam profile for booster packs.
i got lucky getting a rare background image which got sold for 3usd while only buying two cards for 20cents to make a badge.
Repeat the process and may the luck be with you!

a) pick up every free game you can find, idle for cards, and sell them
b) every so often, a bundle could be so cheap you can make a profit by buying it and idling for cards used to be more common, now it's rare but it still happens
c) play games with item drops and sell the items. PayDay 2 drops a safe once a week, SCGO drops maybe 2 cases per week, etc.

get a job
buy 1000 games per month
idle them
sell those cards on the market

or just buy the games you want with your monthly wage, easier than idling 24/7 for some cents.

by not buying games...

If your name is not Gabe, you're missing the best technique...

Basically for me there are two options:

1. sell cards and stuff from your inventory, best way you can get money is to sell carda from summer/winter steam sale events, it wont be a lot but it's an ok amount
2. play games with crate drops then sell them on the market, a cs go spectrum case goes for around 0.25 on the market, and some payday 2 safes go for more if you're lucky. I don't know about other games.
   It's a slow gain.

The only way that pays properly is to invest time in the old method 'buy low, sell high'. Identify games or other high-value Steam items (in-game items) with high demand, buy extra stock (during bundles or other sales) then resell when the prices go up. Obviously, this requires that you spend a lot of time both carrying out the trades, learning market prices, failing and taking losses in-between etc.

Dealing with idling, cards etc. is more of a hobby than anything else. The few cents you get that way will hardly pay up the time you spent. So don't even think about that if you're trying to make proper money.

Find games you might ctually enjoy that have a crate/item system. For example: CS-GO, Killing Floor 2, Team Fortress 2 (I think this one needs that Valve Orange Pack versión of TF2 for selling stuff, not sure).

CS GO drops on "casual" matches are mostly given to the top 3 players I think. Once got a drop that was worth $3 dollars but couldnt sell at the time because of their mobile app restriction which was very new at the time so the crate was worth **** when I was able to sell It LOL!

You certainly need to invest before. CS-GO will pay for Itself with time (get It on a good sale).

Opinions above are pretty good. I'm guessing you're a minor. Idling is not the best way to go, only If you have a súper low power consumption system and yet... on the other hand Steam event cards will let you buy a free cool game at least.

Oh well...you're level 37 on Steam, you have +700 games and have CS-GO, you also trade. DUDE! the next level for you to make profits on Steam is to SCAM people (Kappa).

Note to myself: check profile first before answering noobish questions....

This dude got me good.

Wait for the Valve IPO

After the changes with steam gifting, I wouldn't recommend anybody trying to earn money as a steam trader from scratch. If you have a decent GPU, try some cryptocurency farming, which requires basically no interaction at all once it is set up.

did a video on that at some point:

Right now? Play PUBG, farm coins, buy crates, sell drops. made 12 euros in 2 days.

The hoops people will jump through to earn pennies online.

NOT...

Go play some games and have fun. That's the purpose of steam anyhow.

Moneymaking on steam? Why you should do that? You cannot transfer it to your bank account. So its not really money making because you need to give it back to Valve.
