I have an economic education, so I was quite easily given knowledge about bitcoin. But there is nothing surprising in the fact that it is difficult for someone to understand it at once. All people have different types of thinking, and everyone needs a different amount of time to understand bitcoin.
Agree with you.
As for me , if you like cryptocurrencies world like me, it's not realy difficult to understand it.
For me at first I find it very difficult and hard to understand. I believe it is only suitable for smart and intelligent individuals. But later on, when I get to know more about it I started to understand very well how it is done. Now, I can say it is very easy and interesting.
