well i don't think cryptocurrency is difficult to understand even though it is another system of money. Almost every greener in here might have faced this problem but with determination you will really understand how cryptocurrencies and how they are work.
Cryptocurrency is another system of money. But there are many differences with the money, ordinary people know.
I don't think understanding the concept of Cryptocurrencies is difficult, but most of the people get confused when they bear about it for the first time.
