The key word is "teach" like you just asked. How about teaching others how to do what you want to do for them. You have a brilliant idea do not get me wrong. But I believe in the saying, "teach a man how to fish and not give him fish." I think that is what @oluwoleolaide and @ehiboss is trying to say. Have you thought that one day you will run at a loss if the exchange rate increases and if it reduces your customers faces same. I feel this is a decentralized platform and we all are here to learn from each other. I see nothing wrong in "teaching " people. You would only live to be remembered by the good work you do. Well done all the same.
