The answers I've seen are all about getting randomly dropped cards and in-game items by playing free games, and then selling them in the Steam market for US dollars.
This is an inefficient way and requires a lot of time. If you don't like to play this game, it's a waste of life. Therefore, it is recommended that players choose at least a few popular and favorite games.
In my opinion, there are no such good things on Steam. You want to get money for free, except for the coolie method mentioned above, it is impossible. Because the new Steam account will have a $5 must be spent to unlock your account limit. Otherwise, you can't even use the Steam market.
Proper investment may be the best way for you to make a profit. Steam has increasingly developed into a social platform that belongs to favorite games. Players can find a group of players who have the same hobbies as you in the Steam community, and share game experience, understanding, and fun together. The growing popularity of the Steam community has also made a group of people who want to Buy Cheap Steam Level Up appear. There has also been a platform similar to MMOSO.COM that provides Fast Steam Level Service.
That's right, the business opportunity I'm talking about lies here. You can provide the Steam Level Up service for players by collecting trading cards required for various badges. You can also synthesize badges yourself, and you have a chance to get rare emoji and profile backgrounds, which are much more valuable in the market. There is also a chance to get games or discount coupons. After the level is increased, you can get a refill pack. The minimum value of the aluminum foil card is also in US dollars.
In general, it is impossible to achieve a good result without spending money on Steam. It is better to make appropriate investments. Get rare items at low prices and sell them at high prices. Or provide services for upgrading other players' Steam levels.
