Badges Or Market?

Well, if you are a trader, then yes, you need to have a high level on steam.

You level up and the higher your level is, the more likely booster packs are to drop. It's not really worth the money you spend on completing badges though imo, so I usually just sell all my cards.

For economical purpose, sell them all to market.
For pleasure like me, I'll do as same as a collector with badges and backgrounds and emoticons :"3

Market? pff trade them for CSGO/TF2 keys

My 2 cents:

First of all say hello to your new best friend: http://steam.tools/itemvalue/

My opinion is sell everything that sells for above 0,15( or maybe 0,10) and use the rest to craft badges. There are a few trading groups on steam about fair card trading that will make trades 1:1 based either on set or value so you can complete your sets using other low value cards without those rdiiculous "trader fees". For same set trades you can always try http://www.steamtradematcher.com/ as well.
There's a minimum charge when you list something on the market so selling 0,04~0,07 cards brings back next to nothing.
When selling don't just look at the current price but take a moment to look at the Sale History of that item. Sometimes the current value doesn't reflect the actual price people go for or other times you can find cards of very unpopular sets that take weeks, or even months to sell.

There's always other alternatives too though. Like trading them for games directly, quite a few traders accept them as currency.

Also hold on to your cards from recently bundled games as they drop in price quite a bit for a short time but they go slightly up a month or two later

I crafted a few badges but now I just sell everything once in a while (twice so far, so more like once a year). If I want a new background I just buy it, I don't need super fancy ones so it's around 10 cents and that leaves me money to buy a few games during sales (I haven't finished spending last year's card money)

It was fun for a bit back in beta, but soon after I simply started selling everything. If I could do it again, I'd never have crafted at all. It's a fun meta-game for some, but isn't my personal taste.

I dont see Any reason to craft to be fair .
Someone came up with argument that you need high level to seem more trustworthy , which is the most ridiculous thing ive seen in my life tbh .

Craft a badge if you like a game and want to get the profile background for it ( tho its cheaper to just buy it from market )
Or just craft it if u find a badge funny .... aside of that sell everything imo ...

i liked to craft and collect but then i remembered that i needed the money for other purpouses, so i sold all of my cards and emoticons , feelsbad

I craft badges so my friend list can contain the hundreds of people that send me friend requests.

Badges Badges Badges Badges, Mushroom Mushroom.
Badges Badges Badges Badges, Mushroom Mushroom.
Snaake snaaake.

i mean, craft the badges if you like what they give you.

I just read that and at first I thought it said Bagels or Market lol!!

What I do I just recently got into crafting/collecting badges though.. If a badge costs less than 0.06 cents I keep it for crafting. If a badge costs higher I sell and use the money for the cards I'm needing and also I buy cheap games with it.

I only sell expensive foils and duplicates (the ones left out after I finish their level-1 badges). For the rest, it's just a tedious job to sell them for like $0.04 each, so I'd rather craft badges and maybe get more booster packs, thus maybe more foils to sell.
