Great idea of a contest, it is unique.
An observation, the third price seem to have more value than the 2nd price. Looking at it from the price of steem/SBD and how many steem it will require to get 500 SP for a month at minnowbooster...I may be wrong though.
Well done!
It is not about the cost, it is not about the value...
It is about the weirding ways...
The SBDs are yours to decide, the SP is for you to share ;)
Also the other two prices are convertible to rented SP.
Last time i checked was 200 SP per Steem per week so 4 weeks of 500 should amount to about 10 steem.
Maybe @reggaemuffing can shed some light?
