Hey @arthur.grafo. Thanks for the comment. I'm pleased you found a use for my post.

The Steem you have in your Steem wallet (SteemPower, SBD and Steem) will not be used for voting. That won't be taken out, but the amount you have 'Powered-up' determines how much you allocate on your vote when you upvote someone's blog or reply.

Take a look at this site by @penguinpablo.
https://www.steemnow.com/

Type your username in there and it shows you the latest votes on your blogs, the curation rewards you've received and the upvotes you've received.

It also shows you what voting power you have and how much your upvote is worth when you click that little circle to say you liked a post.

There's a reward pool and every day, it's refreshed. 75% of the reward pool is allocated to authors and 25% is shared between the curators. When you upvote my post for example, you'd get a proportionate share of 25% of the payout listed.

If a post makes $100,

I'd receive 75% as the author = $75

If there were two upvotes and your upvote gave me $50 of the payout, you'd stand to receive $12.50 (50% of the 25% of the total payout).

It's not as simple as that (when is it ever?) but that's the gist.

You don't pay any of your hard-earned steem out, but you can gain some by curation.
