~ Or this rule is applied for the weekly bonus only while monthly bonus rule is different?
I think you will stop receiving the monthly bonus email in the near future. Stake team may come with similar requirements for the monthly bonus. We will see it during the next monthly bonus time.
That will be better if Stake stop sending email about the monthly bonus to those who are not eligible for it because it will be strange if users receive an email with link to claim monthly bonus while they are not eligible for the bonus. Anyway, after 3 months without login, I decided to login back few days ago but I did not do anything (no deposit, no single bet) although I have few dollars left in my account. Who knows that login back will trigger something later, at least an email from them to say "welcome back" lol.
