There a lot of choices if you'll check the threads here in Gambling one by one.
But here are the sportsbook I know that has e-sports on it.
Nitrogensports.eu
Sportsbet.io
Jetwin
Onehash
If there's a sportsbook that I forgot, someone who will post next to me, just add it.
I would add mbitcasino, just remember their name, I think they aren't involved in scam but check yourself OP before decide where to play.
Just to warn you: if you want website with nice template and legit look, I mean 1xbit, don't get wrong and deposit here, they are proven scammers. Also sportsbet.io had some scam accusation threads and their profile is tagged, as I know they work well these days so can't say bad.
Check those websites yourself!
