My earned SBD are mostly traded on the internal market for STEEM, and then powered up. The fraction that I have not powered up has been used otherwise (and you don't need to know why or how ;) ).
Concerning the amounts, note that I only write like 5-6 posts a month, which gives an upper bound on any wallet activity.
Oh I see! Thanks for clearing things up. Follower count really doesn't mean much, does it? I guess I'm just mentally stuck in the old days of Steemit.
Both follower counts and reputation marker do not mean anything :)
