Thank you dear so much.. But why I can't collect fair balance on my posts :(
Really I don't know why?

It depends on who upvote your post. People who has high SP upvote you can give you more money.

I see .. Thanks for your reply dear :)

So.. how can someone increase his steam power?

You earn SP from your posts. Or someone may invest SP from market.
You can search “steem power” to find some posts about it.

Thanks a lot dear :)
