It was removed few days ago, Maybe they are planning to optimizer there betting option since there e-sports coverage is very limited. I remember they only cover 1 to 2 tournament at a time with few options for betting. They are using a 3rd party sportsbook on there website so I believe it will be up for few more days. There's no ETA on when it will be available though as per the moderator. You can use Betfury sportsbook instead while waiting since they are same Web 3.0 casino.
