Is there any official link that contains information on all the Stake bonuses? It’s really confusing for me considering the number of casino I’m active right now. So it’s very hard to catchup on Stake bonuses since there’s no detailed computation on every bonuses.
https://help.stake.com/en/collections/2801356-bonuses-and-promotionsMaybe this page can give you more information about the bonuses on Stake, if you do not find one, simply ask live support but do not expect to know about the exact formula to calculate the bonuses.
In general, the help center page may answer many things you want to know about Stake so you can bookmark it although you can find the link in the bottom of the main site.
Talking about pre or post monthly bonus, the amount I usually get from this bonus is $35 (Platinum V).
