When I was a newbie, giveaway posts were sort of interesting, but these days I just don't care.
When I was a couple of years in, I hosted a few giveaway "challenge" posts, but they were always based on the prizes being based in the liquid rewards a post would earn. Most of the time, my preference was to give Hive SBI shares as rewards simply because they require long term commitments to actually give the recipient much benefit.
I actually had my cat do some of the random drawings... 🤣
The sort of "giveaway churning" you're describing is just kind of annoying because the intent is not really to give anything away, but for the person doing the giving to boost their rewards... usually at the expense of those who know no better. Who cares about winning 10,000 of some 2nd layer token that has no standalone value of its own?
What you're describing that you're doing isn't even on the same planet. Mostly, because it has an actual purpose, in terms of community building.
That's usually my key criterion... is there a POINT to this?
