Strange! Everyone is talking about getting more amount than their expectations. But you have received lower bonus in this time. I guess your bonus was affected by the VIP ladder bonus, which is something new at Stake. This is the first time I have heard about this bonus. Maybe it is related to monthly top wagering activity. How much have you wagered in the October month? Based on my personal experience, monthly bonus decreases significantly at Stake when a user stays in profit within the monthly bonus period.
As far as we know the bonus is based on house edge so every game that we played will contribute to the bonus this means that if you make a profit this month it should not have an impact except when you lose, you will get an additional from the loseback and for this one we don't know the percentage. Of course what is experienced by Bitinity is something strange while we get more bonuses because of the surge in crypto prices, even this weekly I also got more 2x than from last week. I can't assume what the reason is and it would be better ask to support or VIP host.
