It is strange that this post doesn't have comments 7 hours after being posted. I will try to fix that.
HP like any money doesn't grow on trees. So the only options to get it is either to earn by posting/ commenting or buy it.
I was earning more when I was making template splinterlands battle posts but it was not fun. Now when I no longer make those posts I earn considerably less but I have more fun posting. I would like to have much more Hive/HBD. But I can't afford to buy as much as I would like so I have to use a mixed approuch for best results- buying some and earning some as well. Not long ago it seemed that I will fail my 10k HP goal but after a few more suscesfull posts that goal seems feasible once again.
I think it's important to post and comment well and to comment with relevance to each post rather than genetically because that's what helps build relationships and it's relationships that build accounts. Keep up the good work.
