You missed some important points:
-the first cryptocurrency that checked and proved the block chain technology.
-the first cryptocurrency that revolutionized our perceptions about finances and banking.
-the first cryptocurrency that made many people very rich.
-the first cryptocurrency that made financial transactions faster and cheaper (afterwards they got slower and a bit expansive).
-the first cryptocurrency that opened the ground for the altcoins, which are getting more popular these days.
I don't think that learning about a technology that made the above-mentioned things would be easy.
So you right, it is hard to learn, but definitely justified
