It seems that they (Rainbet) are very happy with the marketing promoted by Hhampuz, interesting, I remember when Rainbet started with its marketing on the forum, now they're becoming significant in this community, I don't know the casino, but I know that they are probably reaping great results with the campaign, to the point of expanding the campaign even more.
I prefer the way their campaign make expansion slowly but sure rather than huge expansion at one time and then remove the users who're part of huge expansion, moreover the old participants also get removed because they want to deduct the participants.
I think they should prioritizing high rank users because few campaigns that stopped are participated by high rank users.
Same feelings.
I don't know if that's the pre-announcement for closure or not. Generally signature campaigns which expands its members ended up by shutting down except two from what I recall, the first was banned with the mixers ban and the other no longer pay in Bitcoin. In the past they were two others, one was banned for spamming the forums and the other closed its service indefinitely by the owner and it was the most successful mixer, a decade ago. I feel being an old man witnessing many of these events
