thank you for your comment and for the nice things you said about my post. As to your strategy, that is up to you. I personally think that everyone can do what they think is best. I think you might irritate some authors (not me), if you vote your own comment to the top of the thread and don't upvote the post. Some would call that thread high-jacking... Like I said, I don't mind as I think everyone can do as they wish. And I am not here for the money, so upvoting my post is certainly not necessary.
And yes quite a few people made a bundle during 2016 and 2017... I imagine most made quite a bundle!
Well done keeping the cool Dave. I also don't care too much about it, but I don't think it is a viable long-term strategy. So @julisavio, unless you have a very important point to make it can backlash upvoting your own comment. So that would be my advice. I know curation rewards sux currently, but you will hopefully gain more in the long run by making awesome comments and only upvoting the author's post.
