Re: Here Is One Reason Why Legendary Members Get So Many Merits
...but do Chipmixer participants have more merits? Yes, (96% are merit sources, so getting some is simple), but I can't say the same for Bestchange participants. 
Here is another thought. Users don't get more merits because they got accepted in the ChipMixer or BestChange campaigns. They got accepted because of their merits, which are tied to the quality of the posts they make. Better posts = more merits. Everything else, such as becoming a merit source is just a natural sequence of events. On the other hand, participants of spam and scam campaigns, such as that of 1xBit, don't care about the quality of their posts. Hence, they aren't awarded the same way. You also wouldn't expect them to become merit sources.
