hi @apsu

Thank you for your feedback. I value it a lot.

would maybe try to reach people through commenting, even though it could be considered as spam and flagged

Personally I'm trying to be as little spammy with comments and possible. I don't want people to think of me as a "robot". That would destroy engagement rate.

Sending wallet transactions seems more like spam and will less likely be read.

You're very right. Im still trying to figure out the best ways of promoting myself here on Steemit and this is just one of my ideas.

This is one of the main reasons why I would prefer focusing the rewards to the top, as you don't always get even two good entries.

Again, big thx for sharing your view
