Will be there more slot promotion in the near future? at least restart the multiplier contest or make it an onside contest is fine to make it easier to manage.
How if you create similar contest to the one in playbetrxbetcoin?
The rumor is that they still working on some improvements before launching new promotions since there are many feedbacks from Bitcointalk users. I don't know whether this rumor is true tho How if you create similar contest to the one in playbetrxbetcoin?
There is similar contest when you can win a brand new car if you can be #1 on the leaderboard lol. Oh FYI, I contacted the CS, and they said you can choose to get cash or the merchandise (goods).
We never know who these players are, we maybe don't know, some bitcointalk members also won this programs, we also can't underestimate the members of this forum, because many of them are gamblers with quite high expenses.
It's true tho we can't know the real spending ability of some members here, but for average joes, there are many smaller promotions on BK8 that we can use, for instance the February Festival (region Indonesia) where you can win a brand new smart phone Promotions but only if you lose. If you are a competent player = limit. Let this be clear
most of the time rumor turn into reality if the rumor comes from trusted person.
