Well, I am in no position to talk since we're both circling the same pages. Butin my opinion with some factual basis on what I witness with my co-users that are engaged in a signature campaign, they pick campaigns that are easier to launch and user-friendly, time-bounded since according to them, it helps them save a lot of time. Yes, the tokens gained are of lowest but that lowest is apparently a big one because those little steps can help you step up and be with those expert users.
Hope I helped and I am of benefit. See you next time!
