There is nothing wrong with monetizing a seminar or meeting. These is what most of the experts are doing. They are offering free seminar and the next meetings will be paid but start for a small amount only.

If you are passionate with what you are doing right now then you must learn too how to make money from it. Creating a youtube channel to share some important information regarding Bitcoin will do since your mission is to share anything related to Bitcoin and crypto in general right?

Motivational speakers right now are being paid to speak in different seminars right now. You can do it too. You can browse the internet if there are some seminars and meetings that are related to crypto and you can be a speaker there. You will be paid there and at the same, you can share what you know too.

P.S. I see your passion in spreading the information. There is nothing wrong in getting some rewards from it . Just continue to do it if it really is your passion.
