AFAIK bitlucy still has their Deposit Bonus especially on sports bettors. You can look at their ANN thread here >> https://bitcointalk.org/index.php?topic=5395791.0 . You can try them out as it seems to be a legit growing platform with an active team and support.

But if you want a more reputable platform, sportsbet.io or stake.com are the top sports betting platforms to date with over a thousand daily active and concurrent players. It's just a matter of preferences.
