For doing business in bitcoins, this is a minus, here no one will argue among those who did real business (they are all interested in a stable means of payment). But you must not forget that the "intrinsic" volatile value of bitcoin lies precisely in the fact that it is completely independent of fiat.
What you're saying is it's volatile because it's independent of fiat. You're right bitcoin is but that's not a good sign for some people taking their first steps buying cryptocurrency because they're going to be unprepared for worst case losses.
When you create something new and different from Fiat, then it is quite expected that something will turn out with new properties and, therefore, both with new pros and cons. Accordingly, before working with such a new tool, you should familiarize yourself with its properties, if a person does not do this, then he himself is to blame for the possible negative consequences.
