At least it has something to do with what is being discussed, including the promotion of Duelbits. People are talking about how effective Duelbits is at running such promotions on Twitter and discussing some of the games available in its casino.
We don't have data to analyze it, only the Duelbits internal team have it.
From tip of iceberg, from what we see, they run promotion continuously and it requires big budget. I believe they get good effects, good results, and good income from promotion by acquiring more new users, getting more bets from current users. If they don't have good income from users, they can not have profit and budget to run it months to months.
