You have said two things here. First the title says "Bitcoin is difficult to understand" and now the op is saying "bitcoin is not easy to access".
Well for the first one, you should start with understanding the basics about bitcoin. What is bitcoin, how to acquire bitcoin, how to store bitcoin and some security practices you should adopt to avoid losing your Bitcoins. To be honest, these are just the information many bitcoiners know about bitcoin, it's not that difficult to understand.
However, if your interest in bitcoin is more than just the basics, then you are not wrong, it is difficult. But with time, everything will begin to make sense to you if you keep researching. If diving deeper into understanding bitcoin is complicated to you, why not stick to the basics that is easy to understand?
As for bitcoin being difficult to access, I am assuming you are simply having difficulties acquiring bitcoin because this is what 'access' means. This is just one asset that is very easy to access unlike gold. It is as easy as you getting paid in bitcoins simply by joining a paid campaign here in the forum. Aside this, you can get butcoins from exchanges and through P2P.
