I am the head curator, rep and sponsor for @Vocalists-Trail - which does not belong to me, it is a branch of @SteemTrail who help promote and support passions and the Steemit Community as a whole.
All SP saved on Vocalists-Trail is delegated to @Trail (run and owned by another party).
Admin rewards are half of the SBD post rewards and the other half of SBD rewards are @Trail's.
I am the only sponsor for @Vocalists-Trail, and I designate a share of my rewards to contest prizes.
ALSO
The fluctuating price of SBD and STEEM effect the value of prizes, for instance, 6 months ago posts paid a lot higher. So at this stage the prizes have been adjusted to reflect recent hike in SBD and STEEM value and appear less, but are actually quite similar to past USD value once converted.
6 months ago SBD was valued at approx. $1 USD each
But today it's valued at approx $7 USD each.
