You can show them your transaction history, and then tell them the concept of bitcoin, as well as your own profits, I believe people who have the heart to understand themselves to the relevant site to learn to understand.
I agree with that. And in my opinion, The easy way to teach bitcoin is to try and use it themselves. In that way, they will eventually learn from themselves. It would be more meaningful and undoubtful about what they can learn because they are using and benefiting at the same time.
