There are two currencies Steem and SBD
The third is Steempower. The more Steempower you have the more you can vote with effect.

I have some tutorials on how to add videos and photos. I think they have been negated because you can now just drag a photo or a video into place.

As a new user do you do a post with the introduce yourself tag? introduceyourself.

You should do this post and and a photo while you hold a piece of paper that says the date, your name, and steemit on it. Then you are verified. You get paid more if you are verified because you are not a fraud pretending to be someone else.

You can sign up to follow @steemitboard and @elyaque and they will give you awards as you reach goals in posting.

Everyone else is always lost but there are some true things - title and tags are important. Be careful of plagiarism, if you use someone else's photos or words make a detailed list of your sources giving credit.

More Steempower equals the greater ability to vote for posts you like in a meaningful way.

Use headers - Click the markdown link in Submit a Story, it will list all the markdown language you can use.

Steemit will accept HTML and Javascript as well.

What kind of entrepreneur are you? And I hope this helps you
