steam-trading-cards
My steam level is 2. I don't really intend on buying things to level up.
However, I do vote for the next flash sale item every time there is a sale. As a result, I have collected many trading cards that I supposedly get when I am level 5. Will said cards ever disappear? Is there a deadline for me to collect them?
As per the FAQ page:
Is there a limit to how many trading cards can drop?
Most games will drop a number of cards equal to about half of the number of cards in that game's set of cards. For example, Half-Life 2 has 8 cards in its set, you can receive 4 card drops by playing it. You'll need to collect the other half of the set from other community members. Try the beta group discussions, community market, barter with friends, and trade discussions. You can check how many drops you have remaining on your badges page.
In the instance that a game has an odd number of cards, for example Counter Strike: Global Offensive - which has a total of five cards - the number of cards that you can collect is rounded up. This means that you can get three out of the five cards.
The drop limit is permanent and it will not reset.
However, there now is an additional way of gaining cards:
Booster packs: Booster packs are additional cards for games that will drop periodically. Anyone who has collected all the trading card drops they can for a game and have used Steam in the last week may receive one of these booster packs. These packs contain three additional cards for the game, and may contain foils. If you receive a booster, you will get a "1 new item in your inventory" alert.
These booster packs are randomly given out whenever a badge is crafted (as can be seen by the badge eligibility text below).
As for statistics, there is now also a "How do I earn card drops?" link on the badge progress:
This then shows an overlay with additional information (what earned you card drops, in particular):
A few examples:
All Steam seasonal sales so far with ∞ badge levels:
The Steam Winter Sale of 2013 was the first to set the precedent, in which for the first time both foil and regular badges were able to level up as many times possible during the event. This meant that users could easily complete badges and quickly level up their Steam accounts, without a "level cap" on the badge.
A few examples of users with high levels of badges:
From the Steam Winter Sale on out, most of the other Steam seasonal sales feature badges unlimited levels (exception is the Summer Getaway Sale), so theoretically, there's no limit to how many levels you can get with any of those badges.
Best Answer
Unlike the other steam trading cards the "snow globes" you get by voting have an expiration date which is Jan 03 2014 ,when the sale ends.
Here it says it is valid untill Jan 04,but it is just the matter of time zone.
