steps
1. give asset to the war makers
2. raise the price proposition until they ENDWAR
perhaps they might game the system too
make a WAR seem unendable, asset goes rock bottom, "That's a sure bet that war will never come to peace!"
War-makers buy it up, kiss and make peace.
pay-o-lah!
[repeat]
I don't know where you are getting this give assets to war makers thing. I personally have borrowed some ENDWAR into existence, and begun giving it out on twitter free of charge. So far I have given it to Lew Rockwell, Scott Horton, and antiwar.com. I would not consider any of them warmakers.
"end to hostilites between Saudi Arabia backed pro government forces, and the Houthi rebels"
who determines the truth value?
As the description states the final decision will be with the bitshares committee. The committee is a special bitshares account that has a weighted multi sig active authority that is determined by the votes of all of the bitshares stake. There are between 11 and 1001 committee members with the number and their active key weight determined by voting. To close out this market will require 50% +1 of the voting stake of bitshares. I am personally currently on the committee, and if I am still on it on 1-1-2017 I will vote true on this market if there is a peace settlement or long lasting cease fire, or if there are no reports of hostilities between Saudi backed forces and rebel forces for a significant amount of time.
If you are looking for a means of making money then I would suggest one of the other prediction markets that bitshares has to offer. You can bet on the SuperBowl, Democratic Nomination, Republican Nomination, US general election, Crude oil prices, S&P prices, or the price bitshares. All of these markets will be much easier to close out. These markets might be more to your liking.
