Okay, sure. I see your point. Leave out the word "is" to be factually correct.

Nonetheless I think you're generalizing a bit too much by stating that people are parroting something they do not understand, just because of this wording.

Next to being short for "cryptocurrency", the word "crypto" is also used to refer to the big pile of nonsensical cryptocurrencies outside of Bitcoin. I'm certain that you are well aware of this. 

I'm sure there are plenty of individuals who say it without understanding it, but I'm also sure there are plenty of individuals who say it this way and know very well what they're talking about. 

 most people talking about crypto are referring also to Bitcoin, not only the nonsensical stuff. 

That is what I'm talking about precisely.

Bitcoiners often exclude it, but that's not how most people understand the word.  If we go out of our bubble, people use words differently. If we actually want to warn them, we should use the words to communicate, not confuse. And inside the circle, people already know... 

 I fully agree with you that it's important to communicate in a language that's understandable for newbies, but that's a different conversation 😃.  

 Not only for newbies. This is not a conversation about dialing down on expert language so the laymen would understand. 

This is about semantics of words and basic set theory (something is a node in a set).

Talking in a language that newbies understand is not even it.

We once had a substitute teacher on math and she used the word "or", but she meant "and". Even though she would speak more expert language than us, she was simply wrong, she did not understand the meaning of the word.
