A month seems like a middle ground of sorts

I've seen many casinos running their signature campaigns for as short as one week only, enrolling maybe a dozen posters at the outside. It's an incredible waste of money. In the beginning of the cryptocurrency online casino era, PD had been running their signature campaign for at least half a year (probably, even longer as I simply don't remember precisely), enrolling everyone wanting to participate. I guess half the forum were wearing PD's signature back in the day
