How many steam trading card drops per day/game?

there is only limited drop for each player, if you want as many as possible you have to buy/trade.

You're going to have to spend money then. You have a limited amount per each game.

This kind of proves that Valve know how to exploit us.

Why you no read faq?

There is a maximum amount of drops per game, so after you hit that it will be zero.

You can only drop 50% of the amount of cards for a game. So if a game has a total of 8 cards, you can drop 4. That's permanent. It won't reset. You can drop those 4 in a couple of hours normally, but that's it. You need to buy the other half if you want a badge.

You can read how many drops you have left in your badge progress screen. The cards drop very quickly.

But if i sell the card, i can get another one from the same type?
