I received an upvote of 9.725.

OK, here's the thing - 9.725 is not in US dollars. Those are STUs. They should be equal to SBD but because SBD is not woth 1 USD, it's more complicated.

So even though you see $ sign next to your post payout, this is not US Dollar. Basically it is a mix of SBD and STEEM POWER and sometimes liquid STEEM.

Anyway, 9.725 STUs are worth around 11.16 USD.
So $9.8 -> $11.16
About +14% profit.
