Don't.
The best odds are gone.
Wait for election night when there'll be crazy odds fluctuation - if you bet smart you can make guaranteed profit
There's no thing such as guaranteed profit, if there was, you would take 1 million dollars loan and go all in on your "guaranteed winner", but you will not because we don't know who is going to win.
I also think Hillary will win and it's relatively safe to bet on a Hillary win, but we don't know, Trump may win too, its getting close..
I'm pretty sure that you're missing the point. You can "play the odds" and try to bet such that you're +ev whether Hillary or Trump win - by betting and seeing if the odds change in your favor (you bet on a favorite, and then the payout decreases for them and increases for the other - now you can bet on the other candidate and profit no matter the result)
For example... on the day, Hillary's odds are at 1.98x and Donald Trump's odds are at 1.98x as well (arbitrary example)
You "short" on Hillary Clinton where you expect her payout to decline. Say you bet 10 BTC.
This is the case and then now her odds are at 1.32x and Trump's odds are at 3.3x (like on DB right now) then now you can make a bet on Trump odds to get a guaranteed profit.
If Hillary wins, your prior bet gives you a profit of 9.8 BTC.
If Trump wins, you lose 10 BTC...
So you prevent that by betting at least 3.04 BTC on Trump. If you want a profit, then you bet 6 BTC which would provide the following:
Your total bet is 16 BTC.
If Hillary wins, you win 19.8 BTC - 16 BTC = 3.8 BTC
If Trump wins, you win 19.8 BTC - 16 BTC = 3.8 BTC
Guaranteed profit of 3.8 BTC. Unless somehow the other candidates win.
You can check the math:
To choose a profitable bet with the increased Trump odds... let n represent the amount you bet on Trump
If Hillary wins, your profit is 19.8 - n - 10 (winnings - hedge bet - initial wager)
If Trump wins, your profit is 3.3n - n - 10 (winnings - hedge bet - initial wager)
19.8 - n - 10 = 3.3n - n - 10
9.8 - n = 2.3n - 10
19.8 = 3.3n
n = 6
So you bet 6 BTC. And you get a profit of 19.8 - n - 10 = 3.8 BTC
