I think it might be more like 80/20, so author receives more. Those numbers look somewhat off. ( i am being lazy, sorry).
steem dollars was meant to be 1 to 1 with U.S dollar. So in future, say Vendor sells shirt, he sells in Steem dollar since it always worth 1 US dollar. SBD is a token so its tradeable. And steem is the main token. It get complicated to go deeper. Especially since the 1:1 hasn't alway been 1:1 amongst other things.
And I always use the internal market, there is a link for it, upper right, it is faster to use this than to convert, which I don't really understand myself.
And I just hold SBD's because I sometimes give some out, or use to support projects here on steemit as well as other users.
And you want to hopefully have some steem to sell when prices is higher and SBD's at the ready to buy when it is low. Trading is a whole other deep topic.
Hope this helps.
Hey thanks so much for explaining that, clears things up a bit. I was confused by that internal market as when I was trying to trade for Steem Dollars to promote a post it kept taking me there but finally figured out how to do it.
Glad to help and yeah a bit of a learning curve here. You can ask anytime. Also there is steemit.chat and discord app where you will find many top steemit users.
my user name is the same on both...if your user name is available don't use your steemit password for those sites (just a tip).
