From nothing to something big

I've heard of traders building up from a few cheap skins to a knife, so yes, it's entirely possible. However, it's so much work and time wasted, you might as well just get a job instead. :P

Yes it works, my friend did that too.

it is entirely possible
i got into steam after i finally managed to get some money for The Orange Box (wanted TF2 really bad after playing it 'free' for a while)
2 years later (after they added the trading feature) i managed to get $2000 (cash) along with over 800 games in library, just by trading tf2 items / dota items / steam games with little to no effort, and the only real money investment was the $30 for Orange Box
$2000 in 2 years is nothing, but is extra cash i got out of nothing.

There's no reason it wouldn't work. The trick to trading things is finding someone that values what you have to trade them more than the item they have to trade to you, even if their item has more actual monetary value.

Cat, I yet have to add a credit card to my acc. I never paid a cent on Steam.
It all begun when I saw a TF2 gameplay video on YouTube, and I really liked the game so I tried to pirate it. To my surprise the game was free (actually free not some kind of pay your virginity for a xp boost free) so I installed that "Steam". I discovered TF2 trading and was sad because I couldn't trade my items because of being f2p. Then I discovered Tremor, I did few tasks, got myself an ubersaw and started trading, ubersaw for scrap, scrap for 2 weapons, etc... After a few months of work I managed to get myself a an ubersaw and started trading, Ubersaw for Scrap, Scrap for 2 weapon, etc... After a few months of work I managed to get myself a premium tf2 acc which just expanded my trading, slowly I began collecting games and their card drops. I traded card drops for more and more games on steamtrades.com (rip) and I got myself quite a collection. Then bitcoin promos came in, I got myself a good 25$ from those and spent 13$ to get myself a 10€ wallet code which finally unlocked the god damn market. I really appreciated the market and made lots of wallet from there. 2014 Summer sale kicked in and I Paid 6 (?) keys for Valve Complete Pack, which got me CS: GO so I started safe betting, trading and watching tournament matches for Souvenir drops (got about 40€ from those) in CS: GO. Whenever I get a skin that is worth more than 20 cents I sell it at the market to buy more cards for game collecting addiction. So at this point I just trade so I can get better skins for CS: GO, hats for TF2 or more games.

I did that in the past. It works. You just have to play smart ;) You can't get from a paper clip to a car playing dumb.

Yup! It was called one red paper clip I think it received a lot of publicity which is how it was successful (he got a house in the end). It's feasible for that to work, but not worth the effort and chance of getting scammed.

I had knights and merchants.... they offered me 10 cards. a guy gave me thief collection RU+CIS in exchange for 8 of those 10 cards.
i won

Never played Rotmg then?

Oh, I love that song!
