Maybe my question wasn’t clear enough. I am interested in the theoretical side of things. That’s obvious that at the moment ADA is not very practical as a currency. I can see that. What I am interested in is that if this will change on the long run as volatility comes down, or is there a deeper theoretical reason why this will never happen.
But I found this: ADA: Currency or Commodity? | EP02 | Deep Dive in the suggestion list of similar topics and it gave me some answers.
Since ADA is a platform for smart contracts and there is a large number of financial constructs that need deposits it means that ADA has a commodity value. Now that contradicts the requirements of a pure currency in my view.
Probably it was already obvious for most of you.
