Yes it is understood by many experts that a 'stablecoin' would be actually game changing and a benefit to all, but unfortunately it is hard to make something that is stable through algorithm alone. I think we will have our stablecoin one day though. It will be worth 1 stablecoin each. How much each is, is of no concern because they are the default currency which we all use. Just like the dollar, you don't ask 'how much is 1 dollar'?
Maybe they're right... it has to do with adoption.
But yes pricing something in crypto probably requires some adapting algorithm that changes the price constantly and builds in some kind of buffer in case of volatility.. :-/
