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.
It will always be discussed every month especially if there is something like a cut for the bonus amount based on what users get in the previous months.
Complaints will always come because there is no clear information about how Stake calculate the bonus.
Someone in the Stake dedicated forum say that his previous weekly bonus (last Saturday) was $350 and his monthly bonus is $180, it may make sense if his last week statistic is not included but it does not make sense if his last week statistic is already included in the calculation for the monthly bonus.
Stake should start to reveal the formula publicly and set the date for the bonus fixed every single month.
And I also think it depends on the casino's weekly and monthly revenue as well, that is the profit made by the casino at the end of every week and month, that also can determine how much bonus they give out to their customers .
I dont think casino's revenue has something to do with the bonus, it wont be fair for players who wagered and lost a lot money while the casino's revenue is negative due to other players win a lot of money.
The bonus should be based on user's individual statistic only IMO (wager, profit, etc).
Actually, I had that several times that my monthly was smaller than 1 weekly in the ame period.
I know it doesn't make any sense at all but as I am a 1st row witness of these strange thing I can only perpetuate that.
A friend with a unused platinum 1 account told me his monthly was 1$ now, we had a good laugh. Guess that total cuts are done and inactive accounts are done as well. Platinum 1 and 1 $ monthly, that I haven't heard yet, haha.
. 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.
