The answer is very easy to how could you learn it. Cryptocurrency is the easy way to become rich if you get yourself employed in it. Cryptocurrency is the exchange of digital currency to generate profit.
That is why they see Bitcoin and cryptocurrency in general as an investment and not as a currency because of this idea. Thinking that you will get rich if you invested on it. I'm not against that idea but at least know the main reason why crypto has been created. It is already embedded on the name crypto"currency".
Cryptocurrency gives us a medium to ease our stress from seeking for job outside instead you use your phone to make money while you are at home. I am sure the knowledge and reality of cryptocurrency, will be spread very soon in the world during this pandemic period. We here can show to the world the reality of cryptocurrency.
This is what I like about cryptocurrency. It gave me numerous opportunities to invest in different investments like business, stocks, bonds etc.
Without crypto, I don't know if I can achieve all of that. I have saved money already to buy some things like camera, PC, new phone etc. Crypto helped me to make money even I'm at home. I know that some already experienced what I have experienced too and I'm happy with all of you

Re: What is the Reality of cryptocurrency?
Regarding this, I see 2 things.
1. Crypto is an opportunity for people to earn money at home.
2. Crypto is a way to transact with other people online.
