Whem you write a post, you select reward, dedualt is 50%/50% steem dollar and steem power, you can sellect 100% in steem power or no rewars.
Best way to get max steem power out of your posts is to set on 100% steem power in the right bottom corner when crating a new posts.
SBD's are a better option. Best to go 50/50 at the moment
SBD'S are worth about as much as each steem is. The caveat here:
Each SBD is created and given to you at a value of 1.00 usd per SBD.
So - ya - explore SBD's a little bit more - and see that you can convert your sbd's into more SP.
best regards.
