I will like to know more on the topics that is accepted in leofinance community

Anything finance or crypto related is acceptable in LeoFinance.

My advice would be to simply share your personal journey with crypto.

It doesn't matter if you're still new to the scene, just share your journey as you grow.

also the necessary tags I am expected to use as a newbie Sir?

When it comes to tags, the most important thing is to use a few that are relevant to the topic that you're writing about.

Then for the rest, you can use whatever community tags you feel like - that part is up to you.
