Something special would be to bet on the next LOL or DOTA 2 championship. A lot of crypto enthusiasts are gamers. The pricepool for the 2017 DOTA2 tournament "The international" was stunning 25 Million USD (source

I'm not sure if there is any possibility to bet on esport yet.
I second this.
Never in my lifetime would I have thought that "eSports" would become so legit and mainstream. Think about a decade ago even, there were barely anyone in the world making a living only from playing video games professionally and now we have $25,000,000 tournaments?! Incredible.
I think lots of younger folk would be betting on these things.
Yes you should consider E-sports, you totally will have a market worldwide. I do not came across a site that allows us to bet on our favorite team and if you add it you will be first of its kind.
Also you may add boxing and MMA fights i know the competition is tough on those sports but I am pretty sure there will still be bettors if your market is worldwide.
Good luck to your project.
Another person interested in e-sports. Interesting. Boxing and MMA are definitely very popular. Thanks for your suggestions, and thanks for the good luck message
