you need Hive to post vote and comment, So when you get your first rewards in a week I would power that all up. To get you started I have sent 15 Hive powered up to your account. That should help a little you need to get to at least 50 powered up hive to be able to post, comment and vote on a daily basis.
Let people know what you like and don't like in an introductory post. Yes you can post your nudes, just make sure the first tag is NSFW. For crypto stuff there is the LEO Finance Community https://peakd.com/c/hive-167922/created, you can post and find a lot of crypto information there.
