There are some folks who will figure out not to trade and not to shitcoin without actually doing it, but yeah, a lot of folks also will get sucked into it, and surely some folks learn faster than others, and some folks keep making the same (or similar) mistakes without learning their lesson.
But, yeah, people tend to have a lot of pride, which is not necessarily a bad thing, so they will tend to want to think that they came to the resolution on their own rather than someone else telling them... so it can sometimes be difficult to figure out how to give some guidance while letting the other person come to their own conclusions.
You are right about all you said here sir, one thing I have seen in our society nowadays is that not everyone has the same speed of learning, some people even tend to know the right thing very quick but their stubbornness makes them refuses to accept the reality on ground, and sometimes its pride that is the major cause of such attitude, because since they were a top critique then, they were hoping for all they said to play out, but since it didn't goes as expected, and they saw that it's totally different from what they thought, it mostly takes those types of people much time before joining the moving train because their pride has been bruised.
Just like most of this big organization and government that are investing into Bitcoin today, they got the first hand knowledge about it earlier but pride and stubbornness are the primary reason they are just coming in now.
So what you have said here are the pure truth, at the end of the day, on their own pace, they will start investing in Bitcoin without anyone convincing them to do so.
