The current bear market might have contributed a little, especially if there is indeed a correlation between the market and the number of running campaigns. But if there is, the relationship is most probably indirect. After all, if the revenue of the casino is significantly growing while the campaign is running, I don’t find a reason why they should stop the campaign, unless perhaps they have somehow established that their casino will continue to thrive even without the campaign, or that the signature campaign is not really a factor in their growth.
Although it is not that interesting to speculate because it is more of the rule than the exemption here. Long-term campaigns are far outnumbered by campaigns running only for a few weeks or months.
