It is likely that in the coming weeks Rainbet will continue to expand their campaign by adding more participants, making Rainbet the largest campaign by number of participants.

As the exposure of the signature campaign on the forum is high that the expansion is done several times by the manager, as they keep focusing on the signature campaign rather than the contest.
They are certainly trying to test out if the signature campaigns are a little more effect that the contests they tried to run. To be honest, the contests weren't really bad, but I think they attracted only a small audience vs those from the signature campaign. But anyway, the casino is fairly "busy" when you look at the live bets especially the slot games.
