The resource thingy you have grows when your HP (Hive Power) grows. It'll take a bit of time. HP grows with post and comment rewards. 50% of the $ value in rewards goes your way, 50% to those who vote. 7 days before rewards are paid out. I guess perhaps some more detailed stuff to tell, but isn't necessary to know.
But one thing, you can cast about 10 full (100% votes) a day. Well you can cast more, but your energy (this is something else to resources) is slowly regaining and this is about 20% of your total resources, per day. So what most people do is they cast max 10 votes a day. Well, if you vote 10 times in a short period, you notice you can vote 11 times to come down from 100% to 80%. This is because each 100% vote takes 2% of the current energy value down (also called Vote Value).
Don't think you break community rules. But not sure. You post your music in the MUSIC community and they don't have many rules. I think I am listed as moderator, not sure, didnt check last year or more. Am not really active over there. Well, that said, I am not at all active in posting as you may see in my blog {LOL}
To gain more attention? Well there are not set rules to that, but as in any social media, and especially on HIVE, best is to become active in the comment section of posts by others. I suggest to go for some meaningful comments. You'll notice quickly enough if a specific user likes such, or not. The smaller accounts may follow you much more quickly than the larger accounts.
Another way to get attention is to enter contests and challenges. That was the reason why I mentioned them in the comment above. VIBES is doing very well. Well, I suppose because large vote values are given to plenty of contributions,. But they have quite strict rules, I believe. VIBES is as far as I know about performing music. Maybe take your guitar and sing a song and post to 3Speak? 3Speak is our video platform for which all posts end up on the same HIVE chain in the same blog you have. Perhaps Ecency also supports video, dont know, never used it and never looked in to it.
It also helps to spend real effort on the posts itself. Especially curator teams (those who can give considerable amount of value plus a ton of followon votes) do like to see effort going into a post. Effort can be a lot, but my take is textual effort. No AI stuff and all. But more personal or personalised stories, ie no journalist or 'cold' type of posts. But that said, it depends on the topic. I mean in the science part of our community they like factual, insightful textual posts from which other peeps can learn. My personal take is, whatever can be found on the Internet, in Wiki and such, hasn't much value on HIVE. But hey, that is my opinion {LOL} ... I seem to get overboard with the effort I put into my posts, with like 2000 words + {LOL} takes considerable time to create but ok I seem to post only like every other month? {LOL}
NJOY this Sunday and your time on HIVE.
