I have been doing some research into earning more bitcoin that just through Steemit. Here is what I found....
Faucets are websites that say they give away bitcoin to random accounts that are signed up when you give your wallet address and email. I wouldn't say your earn bitcoin, but more than you win bitcoin. Sound like you will have your email sold to marketers.
Of course there are gambling websites that will change your bitcoin to Casino chips. You probably don't have the same odds as a Las Vegas casino, but at least you don't have to pay for a hotel room.
You can sell advertising and get paid in bitcoin, this is only an option for people that can build websites that people visit. In my experience, it is extremely unlikely that you will have a website that anyone would want to advertise on.
Please post the link to your favorite website where you can earn free bitcoins all replies will receive an 👍up vote! ( a up vote from me is the next best thing next to getting free bitcoin)
