You're doing good work. Look at the people in Zimbabwe paying as much as $13,000 for one Bitcoin, this is as of November 16, 2017. There will be other countries with fiat troubles that will need Bitcoin or the altcoins.

There is another book that might help you, it is called, Pitch Anything by Oren Klaff. I have gone over this book multiple times. I think it would help you a lot.
