The channel already monetize.

Right now I am just thinking of how I can deliver better videos. But obviously I don't know what I don't know. So I need outside people to tell me what they think.

If possible, I'm trying to find out if my videos are quality enough, and what other types of topic do people want to watch. I can go more economic, more finance, or more personal finance like FF.

But honestly not sure which one will be better.

So your suggestion is that i go towards the "how to trade" direction? Btw, i earning about 30usd a month. Right now my cpm is i think $2.50. This one no issue I can just share. Doesn't mean much to me.
I will start open tiktok account soon 
Yea I also do that. I reduce a lot of the content to very simple words already. Like the usd vs brics topic I made. That one turned out quite well for my small channel. I was thinking of doing more of those also, but that would bring me towards the economic path.
Of course I believe my content got value. But whether other people think it got value or not is different case. That's why I need to get feedback. See whether I'm doing it right or not.
