That’s fair enough. The 50/50 split pays 50% of the value in Steem Power & 50% in SBD.
SBD is meant to be pegged at $1 so a $100 post gives $50 worth of Steem (Steem/7 Day market average)
& 50 SBD.
The peg is currently broken and SBD is trading at $6.12 as of writing this. The post value estimation doesn’t take this into account so that 50 SBD would be worth $306 + the $50 worth of Steem (Around 8.33 Steem.)
Hope this helps.
