On this post I upvoted by 2.3SBD and the rewards are as follows:
1.08 SBD, 0.50 STEEM, 1.16 SP ...and that is before curation.

In USD it looks like this:

2.3SBD = 2.85 USD

Rewards:

1.08 SBD = 1.35 USD
0.50 STEEM = 0.79 USD
1.16 SP = 1.83 USD (if powered down)

TOTAL = 3.97USD x 75% = 2.97 USD.

Which gives 0.67USD or 29.1% profit.

Correct me if I am wrong please....!
