Below I will share a step by step on getting free games from steam & steemit using bitcoins.

1. Create a steemit account
2. Post regular content that you're interested in to your steemit account, as well as commenting on other's content you're interested in.
3. Wait for your payout from your content to match the amount of money needed for the game
4. go to blocktrades.us and get a deposit address to convert your SBD from steemit to BTC, and have it send to your bitcoin wallet
5. go to steam.com and pick out your game
6. When you're ready to buy the game select bitcoin as your payment option.
7. Walla, you have now purchased a game with the money you made from writing about the things you love on steemit. I have used this process coupled with moving my money to an exchange to trade for profit and purchased several games this way.
