Yeah, I really like the Bears move in getting Mack.
Betting hasn't started in full yet, the team is really working on the platform itself with constant updates. They do have an esports betting license and have trialed the fantasy sports feature (also comission free). We have gotten over 20k users so far and the design is really strong.
If you get a chance, I would at least reserve your name. There have been some people taking Steemians names. We are cracking down on those abusers and it's working well, but I would reserve it and do an into post just to claim your name and to get some Scorum rolling in before the advertising platform launches which will give income to active users.
