I've come to realise that many people still don't understand that there are other cryptocurrencies apart from the bitcoin, yes the bitcoin is considered a cryptocurrency but they're two things altogether, bitcoin is the supreme digital currency and all digital currencies around the world are known as cryptocurrency,
Bitcoin is a cryptocurrency, it is one of the cryptocurrency.
And other cryptocurrencies beside Bitcoin is called as altcoins (alternative coins).
I think so far that is what I have learned.
And I think many people actually understand this.
Your analogy actually adds to the confusion. ha ha
