Do you think if someone knows about bitcoin and just spends time learning about the technology and how it works without taking advantage of it to make a profit? I don't think anyone can do that, especially young people who always desire to get rich and even have the idea of getting rich quickly.
It’s true that some people are too greedy but I don’t think that that should hinder them from learning about bitcoin still. Greed and impatience can be changed over time with effort and dedication. New knowledge is always helpful if we just learn how to manage and control it.
Besides not a lot of people would be able to invest right away no matter what they try to do due to lack of funds. Still it’ nice to have that knowledge in store.
