I think wagering has a relative impact on final bonus, since deposits and money lost made the biggest part of bonus.
Perhaps the monthly bonus is a little smaller than other occasions, it is always a great incentive that they provide.
And I think it also depends on how much a player lost as well within the week or monthly, those who lost far more than they won are likely to get a hire bonus, compared to those who won more than they lost, I think this is just a common sense, to try to atleast, give something back to those who must have lost more.
And I also think it depends on the casino's weekly and monthly revenue as well, that is the profit made by the casino at the end of every week and month, that also can determine how much bonus they give out to their customers .
. Although I've predicted that I will get lower monthly bonus but I did not think that it will be this low. I thought that it is only me who think that this is the lowest monthly ever, but after reading some post in the stakecommunity forum, I see that there are many others who are also thinking the same. Maybe the fact that we got 2 monthly bonuses last month and the fact that Stake was robbed $41m also affect this September monthly bonus.
