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.
You are very correct with hundred percent that people show more concern when they hungry to know the things which will be very helpful to them, i come to understand that people that things More serious if actually they paid to gain knowledge or get any update by their own money than if someone or their parents paid for them to learn the work because as our faces defer that is how our characters defer to, so there are categories of people that doesn't show interest in things that can be beneficial to them future, all they are after is looking for someone to give them money, while there are some categories people that are willing to learn but no sponsoray, so i still stand on the ground that if someone meet you to help him with Bitcoin knowledge that he is ready to learn please do create time to teach the newbies all he requires to learn.
