According to the bookies, it's not a slight advantage on Trump only, but he is the heavy favorite.
And there are still 3 months and half to go before the election start, but the odds now is really unprofitable to bet for Trump, the odds will keep lower and lower, probably it could reach -400/-500. But, we still didn't know yet whether there would be a sniper that want to hit Trump.
If there is another attempt, I'm sure it will not succeed as Trump's team is now more careful after what happened recently. The odds may not be so attractive for most of us, but if you truly believe that Trump will have a landslide victory, you should be confident in taking that -400 no matter what. After all, it's still a profit in the end, regardless of the amount.
Hopefully Duelbits will give odds boost in case they added US presidential election event.
If they'll give that boost, I don't think there's a significant effect on the heavy favorite odds, but an increase of odds is still extra profit, so let's get it!
