Cryptocurrency is introduced as new currency. It is necessary to know about it because it helps in future. In future we can pay bills through Cryptocurrency and this feature started from last year. Many companies, hotels, shops Accept Cryptocurrency as a cash payment. I have shared BTC information with my neighbors and they are interested in Cryptocurrency. I only gave them hint now they auto search on google and youtube and they are learning about it.
But what about illiterate people who have no trust on digital currency? It is so tough to teach about digital currency. Besides, we have to teach them about the risk of investment also. If we able to teach them both pros and cons of Bitcoin, I think they will be able to adopt with it easily.
