I would agree with sticking to what you know-- or at least what interests you, because your passion for what you're covering will come through in the content. "Fad chasing" might earn you a quick buck (or not) but it's all but impossible to build a genuine long-term following if those followers never know what you're going to serve up for them next.

I post what i know ,  make  a post about crypto and steem need some level of knowege i just dont have , so better post what are you good in !

Build it and they will come.

It's probably not a coincidence that the trending page is dominated by users with high reputation numbers. Mostly 60's and 70's with just a smattering of 50's. Almost nothing lower than that. And pretty much the only the only way to earn a high reputation number is by posting quality stuff. A chicken and egg situation.

*"the harder I worked, the luckier I got..."*

Or...

*"Luck = preparation meets opportunity."*

Keep investing in skills, knowledge, and practice of the craft... experiment... find your own voice and write authentic, valuable content... become a student of value, and commit to continually increasing the value you deliver, and luck will not be needed - for you will attract the rewards earned through the process of increasing your value to the community... ;-)

The whales don't feel any need to give you a little hand job here so you won't be getting into the trending page.  Now if you were worth sucking up to, chances would be much better. Not just you but myself and pretty much almost everyone else around. The answer though isn't to get all disparaged about it but to become a heavy hitter.

I get this.....well said :-)

I could not agree more. Creators chasing trending topics is what destroyed YouTube for me as a viewer. Instead of getting original, fresh and authentic content, I just got the same videos over and over on the same topics. Just because all the creators were chasing the money. And now look how that's going for them.  Just focus on doing what you do best and giving people quality content that adds value to their lives, whatever that value might be. Just my 2 cents.
