I think you have already been informed well. Resource Credits is a kind of voting power but for publications/comments/votes/transfers, and in steemd in the RC box you can see the amount of comments, publications, etc., that you can make.
But in general there is a lot of confusion, the best thing you can do is to see @steemitblog 's latest publication.
And on the price of Steem, it dropped to $0.50 and then with the HF20 it went up to $1, although Steem transactions are now paralyzed in several exchanges like Bittrex or HitBTC.
Thanks @vieira. NI’m not sure what the full path is for steemd. Is it a dot com? I just bought some steem on Bittrex with no problem. What do you mean by paralyzed?
Yes, here is the link.

Yes, you can buy and sell Steem / SBD in Bittrex, but you can not make withdrawals or deposits, that's what I mean, that locked-in capital may have to do with the price.
