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.
Even though Bitcoin is a cryptocurrency, you should know the right time to refer to Bitcoin as a cryptocurrency, and since this thread is for Bitcoin investment and discussion, it is not advisable to refer to Bitcoin as a cryptocurrency so that newbies who are starting their Bitcoin investment won't think Bitcoin is the same as shitcoins. It is always advisable to refer to Bitcoin as Bitcoin for newbies to know there are big differences between Bitcoin and shitcoins, and it will help them not to invest in shitcoins unless they choose to risk a few dollars in shitcoins, and they will be responsible for any losses they incur. A bond isn't a digital asset because it entails lending money to a company or government in a given period, and you know you interest at the end of the period.
