It is a natural phenomenon that people take things more serious if they are in need of it and come to you than when you are trying to convince them to have such a thing. It's just like someone who wants to learn a trade, you will be the one to go to your master and register your interest with him. It won't be the same with someone whom the master is trying to force to come learn the trade. It is never a good idea to meet a newbie and try to convince them to invest in bitcoin. But if the newbie comes to you, try your best to teach him all he wants to know, that's were the seriousness will come in.
Yeah, it is good for whoever that wants to learn to seek for it instead of you to meet and teach them just because you want to help them because humans are ungrateful even we you have genuine purpose for wanting to teach them something you know it will be helpful to them especially those that relates to money. Anything concerning teachings about money most people feels that you want to scam them or there are benefits you will get from them for teaching and advising them to invest that is why no matter how good you are in any field, never try to persuade anyone to learn or do what you are doing to be successful, just allow them to come to you then you can teach.
