cryptos are difficult to understand at first. But even fiat money is quite difficult to understand.Frankly speaking when I first heard about bitcoin which was the dominating crypto currency  at that time, I was fascinated. I kept on asking the friend who told me the revolutionary journey of bitcoin from zero to where it is today. I had never heard of block chain or bitcoin at that time. However I started to learn about bitcoin watching tutorials and exploring it all over the internet.So what I am trying to say is, to learn about crypto currency there should be the desire or the interest.
