There is a famous saying "give a man a fish you feed him for a day. Teach a man to fish and you feed him for a lifetime.". Likewise, if we start thinking from our own brain then it might take some time to develop good critical thinking skills but once they are developed they will be with us for life. There is no use of following other advice or signalling group.
One need time and dedication to validate information that is at his disposal. Since there is lots of information floating around, we need to separate the real one from the garbage.
All this will help in developing skills that can judge whether the logic presented in the source (news) is valid or not. May be in start we get no good results but with time this approach will mature.
I heard what you said differently. An older brother of mine used to say this saying, his morning was like helping with deeds rather than with money. If someone is helped with money, he will spend the money for a time and he will need money again and he will ask for help again. If he can be helped with an action, the action will earn money so that the person giving the advice will not need to be helped a second time. Although the word is short, this word has been used enough in every case. A new person expressed interest to know about investment or wanted to know about investment but we only discussed with him the positive aspects of investment only to weaken him towards investment so that he will enter into investment with wrong information or wrong idea.
Before investing with an investor, one should discuss the financial situation after the investment. The new investor should be given a fair idea about the investment and although time consuming, the investment should be explained to him in such a way that he does not have to ask about it again later.
There is a government run program in my country (Pakistan) with name BISP. In that scheme government only give money to people who live beyond poverty line. Its now largely criticised that rather giving money to people, government must spend same amount on running training centres where people will learn some skills that will help them in the long run. That scheme so far was not successful in improving financial condition of people since they spend that money every month and wait for next month instalment.
In case of Bitcoin, its necessary to teach person how to rightly invest. If a person understand that what Bitcoin investment is and how to do it rightly then it will help him in the long term. Of course it will take time but once a person mind is matured then he can do it on its own without anyone assistance.
Every picture has two sides and you rightly said that we must tell both sides of Bitcoin to anyone we advising about.
