Not all people are like you or us who easily understand bitcoin, there are others who even though they read the simple meaning of bitcoin and its function, there are others who do not immediately grasp what they have read.
This kind of condition can only be overcome apart from learning for theory then we must at least try to practice to do it.
Bitcoin will forever be considered difficult when we don't want to try in it because in the end the learning or research we do if it is only limited to theory without knowing more about what is happening then everything will not be much different because we only see the shell without daring to change it with the content carried out in practice in the end.
Many people say bitcoin is difficult just because they don't want to try more because of the fear of losing their money so in the end things like that will never change if indeed we don't want to try something we couldn't do before. Getting out of our comfort zone is important if we can't then learning is the solution, now there are so many references that we can do but if it is done but the fear is still in us then everything will remain the same because it is not bitcoin that is difficult but we are too afraid to start it.
