Hi there, i am here to teach you how to make steam cash by using free game's trading card drop system.
This will not bring you a large sum of money. It will manage to get under at least under 2.00€ or $ or £.
You also need to have a Mobile Authentificator turned on for at least 7 days.
Step 1 : Pick a free game you like!
There is a variety of free games on steam, you can pick games like Tam Fortress 2 or Unturned
Step 2 : Start playing the game!
I have played Unturned
And i have played for 48 minutes and i earned three Trading Cards. Their price were from 0.11€ to 0.13€, a reasonable price isnt it? But remember, prices can change every hour or day, so ypu might not encounter this price.
Step 3 : Sell your Trading Cards!
This process is very simple. Just go to Community and Market. Then click "Sell an item". Then click Steam and click on your cards. Then click sell. Remembee, you need to set a price from the currency feed.
Congratulations! You earned money by playing a game.
If I recall correctly, you do not gain cards from games that are free in the store unless you pay money for it. There are games given out in giveaways throughout the internet that do drop cards though.
