This is great helping the Newbies to learn cryptocurrency courses is awesome, this  will actually help them build their knowledge and give them better understanding about  cryptocurrencies, and the fact that your doing it for free makes you  a kind hearted person but it's so unfortunate most people don't value free things, like some who would join won't want to take it seriously because there didn't pay a dime, but it shouldn't discourage you rather teach the serious ones and in time to come you would reap from the teachings you gave out, like a friend of mine will always say we rise by lifting others.
