This is going to be a very basic guide on how to get free steam keys.
Some sites give out free keys and do giveaways.
These aren't the only websites that give out keys and there are plenty others.
If you want to find more of these keys I would suggest going to d3scene as there are frequent posts about free keys and giveaways.
And with these keys you can go ahead and sell them for whatever you want like paypal, btc, and skins.
I hope this helps ya out.
