They’re not saying something else nor denying reality.
To be clear what they are saying is “Bitcoin, not crypto”, making them into distinct classes; ie different things.
That both words refer to cryptocurrencies is not the relevant point of the statement. “Gold, not metals” would convey the same - it implies a distinction and delineation in what the speaker is referring to, a superior/inferior.
I know some languages would equate “not” to simply a negative of the following word, but that’s not how it’s being used in this context in English.
For the third time: I am not criticizing "Bitcoin, not crypto". I am criticizing "Bitcoin is not crypto".
Then you are tilting at windmills because that is not what someone saying “Bitcoin, not crypto” is meaning, as I just detailed for you.
If you’ve explained it three times and you think everyone else is wrong, perhaps it is indeed you who has it backwards.
You are still talking about "Bitcoin not crypto", I did not post about this. The original post was about Bitcoin is not crypto, which I keep hearing (last time yesterday in local 21 group), that's why I'm writing about it.
if you mean Bitcoin not crypto, don't say Bitcoin is not crypto, that's all.
