I'm planning on opening ~3 new markets for propositions which will end before May 16, 2016.
Possible markets that I am considering are "result of Pennsylvania Democratic primary" (ends April 26, most contentious of upcoming primary) and "Bitcoin price on 4/20/16" (Wedge convergence on 4/15 is leading to a large amount of speculation on where the price will go from there).
Does anyone have any other suggestions or comments on the markets suggested above?
