I believe, aside their regular promotions (their weekly, bi-weekly) that are already in place, they can always come up with a new one.
From time to time, they need to offer something different to keep up the interest of players.
These farming, staking would be very productive if their token itself is growing in value.
And that is, collecting active players as much as they can. The competition is getting tough as there are new casinos created everyday.
Maybe they will launch a new promotion/contest with the upcoming US open. I think it is some what necessary to boost the activity on the sportsbook as they haven't done anything to really promote it (except for some boosted oods).
