We are are group of people who absolutely ignore the campaign that does not guarantee a predictable reward. I may have joined a few in past but for last two years, I haven't joined any campaign that does not limit the number of users or guarantee a fixed price of token that could be precalculated. They might be a difficult to find but there are plenty of them.
Sure enough, I always followed a bounty project that provided limits for participants because in my opinion this indicates the burden of a project to pay participants in the future, but maybe now it's more difficult to find a good project in my opinion because even though the system is like that still the volume is different from before
