The true fact is that bitcoin and other crypto coin are all called or classified as cryptocurrency however they are not the same they are totally different from each other
For the sake of newbies, it's better not to use the term crypto currency to address Bitcoin as this can often turn out to be misleading and pass the wrong idea about Bitcoin. I feel it'll be more appropriate to call it a digital asset instead of crypto currency as digital asset best describes the nature of Bitcoin and not crypto currency. Using the term crypto currency will only make people see or compare Bitcoin to all of them shitcoins, which is not only an insult to Bitcoin but also the biggest misconception an investor or anyone would have about Bitcoin. So it's best to completely avoid the using the term crypto currency when talking about Bitcoin.
I largely disagree with you on this one, Bitcoin is a crypto currency as well as a digital asset, do you know what else is a digital asset, the so called shit coin, NFTs, gift cards, shares and bonds, e.t.c but guess what, not all are crypto currency, heck Bitcoin is more of a crypto currency than a digital asset.
Do you know that Alibab, Amazon, and some e-commerce websites are all digital assets to their respective owners, if the site shuts down, that's the end of their business, or source of income.
