That's the thing about Hive. You can do a lot of different things (and earn HIVE a lot of different ways), all from your single account.
Here are a few things you can do with Hive.
Do you want to write or read content? Check out the PeakD front-end and find the right community for you. You can earn HIVE by both writing and curating.
Maybe you're a video guy? 3Speak is a decentralised video platform. Again, you can earn HIVE here through both creating and curating videos.
You mentioned that you're a gamer? Have a look at dCity, a basic city building type game where you can earn HIVE more passively.
Of course this is just a taste of what you can do with a Hive account. Good luck!
