I think you have left nothing untouched which i can share because I am a minnow myself.However still i'll try to advice just to satisfy myself that I am not hiding anything inside because that will amount to selfishness.
Here is what I realised, minnoww should do.

• Don"t expect to be millionare in days-- I mean don"t expect your posts to earn dollars like whales because that is frustating.
  You can also earn but it takes time. You should check the joining date of those dollar earners and you will realize that none among them has joined a week or month ago, but at least near about year ago.So you too need to wait at least half of that rime-6 months but that time you will understand what and how to do.
  *Minnows start your earnings from comments but remember to make quality comments.For minnows quality comments means-not to write comments like " wow nice post, good post, informative post etc"
  These commemts are not going to help you.
  Minnows make such commemts with the aim of making short but many commemts but that ia not going to work.
  *What to write then- read the posts you know you can comment on, carefully and then add a comment which adds value to original post-comment which may add something or may include constructive criticism.
  *Don't write comments with the aim of earning something on every comment even if you make quality comments.
  *Be consiatent even in making commwnts- I mean make quality comments on post of people regularly so that they notice you.
  *Make good quality posts..Making a one quality post in two days is better than making 2 low quality posts in a single.By quality posts i mean informative, free from.plagiarism, original, good length, well formatted with audio-visual support.
  *Make friends on different discord channels which will visit your blog and support you.
  *Discord has certain free upvoting channels like PAL, INDIAUNITED, STEEMITCHAT.Do join them.Sometimes they are the only supporters initially.
  *Take part in challanges like colorchallange, photobombcontest, meme contests, comment challanges like this ppst, daily brain games challange etc.But be original there.
  *Try to learn something new everyday.Somethings every minnow needs to know like Markdown editing, image use-free images, image source and text source,
  safety and privacy rules. source
  *Work sincerely and work hard with zeal and enthusiasm like.I AM WORKING RIGHT NOW.I AM TRYING TO MAKE EVERY POSSIBLE.EFFORT TO WIN 5 SBD (lolx.....just for fun).
  *Be persistant/consistant because initial weeks/months are frustrating.
