"Stable coin" is one of those misnomers where it means exactly the opposite of what one would expect from the existing definition of those words.
Something pegged to the US dollar is inherently going to be unstable, because the dollar is unstable. The dollar is not priced in terms of dollars. One dollar today might not be a dollar tomorrow. The instability is mostly due to the conditions of the market, but then those effects are compounded by the whimsical economists printing it for fun.
OTOH, Bitcoin is a closed system. At any point in time, you can measure the amount of Bitcoin you have as a fraction of the total amount of Bitcoin which exists, and you can even directly predict how that will change due to inflation for the next 100+ years.
I personally prefer the term "fiat coin" or just "shitcoin" is sufficient.
