After holding the meeting a few days ago, the guys we talked to have been on our nerves. We aren't surprised tho cause we saw it coming. They come with different questions at different tines, phone calls and all, and there's no way we would refuse to continue tutoring them. It's not like I don't have the time but.... Something like this, isn't it worth being paid for? I mean, we informed them for free, and we gained nothing (just went back to our houses) and even after then, they still come with different challenges.
Some of them who were there when we announced the meeting date, they didn't come but still come back individually to request explanations. So I ask, is it wrong to monetize a bitcoin/cryptocurrency seminar/meeting? Cause we've gotten nothing for as long as we've worked.
Well,never share your phone number with many people.That's my first rule.

Second rule-If you wanna tutor those people without having to talk with them,just write everything you have to share in one ebook and share that ebook for free.You can include a "frequently asked questions"(FAQ) chapter in the ebook.
There's nothing wrong to charge a fee for your seminars,but your audience will be way less than before.
