Nope. All 4/5 that i have invited didn't stay too long, and that was with my support when I had 10k more in delegation, and STEEM was 10x this price.
A few people i know are earning sweat-coins for exercise, and I think i'll have a go at getting them onto actifit when I see them next (Will install, create account, give them the right key etc).
Turning up without a plan or stake these days is going to mean a sharp exit imo. And they still do, cause of that excellent shop window 'we' have called Trending.
"All 4/5 that i have invited didn't stay too long..."
This is one of the biggest problems because the vast majority of them feel unmotivated (mainly because of low currency values). However, a part of it's their own fault, because they already assume they will be rich.
