Why do people have so much confidence in the crypto currency?

This way lately, every day I meet with more and more people who are convinced that the crypto is a currency fraud, and now I have decided to write this article on this topic, in general I do not mind when people are against something and do not like something but I do not care when they start to convince me that what I'm doing is wrong, but I do not waste time on convincing other people into a crypto currency, I just want to share knowledge with people who are interested, but those who do not want to The acceptance is so persistent that they even started and insulted, the essence of all this is that most people always always get into some good things and good jobs, so they are always losing their fears and not the vowing of "perfect" solutions.
Do you have similar things happening to you and how do other people react to your environment when you talk about crypto currencies? Do they react as if they were from the primers or were they inquiring about technical matters?
