I have been in Bitcoin for years. but I am more closed and silent. I don't promote bitcoin to people around me. Because bitcoin has a risk I'm afraid that I'll be blamed if there is a loss ... because most people don't want to take risks.
That is a reasonable reason on why you do not teach others Cryptocurrency. I also do that with my family members because I am scared for getting blamed if they loss their money for doing something rashly within the Cryptocurrency Industry but I believe that is a risk everybody would take when they are gonna learn about Cryptocurrencies. Its also easy to tell them that earning this kind of money will come in great risk but you could also teach them a safe way to earn money within this industry like joining campaigns that you only need to follow the weekly tasks needed.
