Bitcoin is not difficult it depends on the person you're learning from.
Everything is difficult but a good tutor can make things easy for you. I learnt Bitcoin from a friend and he taught very well, even in school a terrible teacher can make a particular subject hard until a good teacher comes in and make it easy
I think in this case it does not depend on the person who teaches you but depends on yourself whether we have tried to learn bitcoin properly or not.
Expecting good learning from others but we cannot take it then everything will remain the same nothing will change from it because it all depends on ourselves.
In addition, learning bitcoin is currently very varied, not only waiting for other people to give us their learning because as long as we are equipped with supporting internet, all the information we want to know can eventually be easily obtained including bitcoin itself.
Bitcoin is not that complicated, it's just that we are sometimes too lazy to look for references to support our curiosity which actually makes it seem like bitcoin is very complicated to learn.
