Maybe a mix of both, with some tokens being the "main currencies" and all the others being interchangeable.
I withdraw $100 from a small bitcoin wallet via ATM 30 mins ago, and just ordered breakfast at this coffeeshop where I am writing my comment. So the money is all feeling interchangeable for me as long as I can keep getting coffee with it :-D
As far as DASH goes Im not holding any right now but I'm only holding two tokens - mostly Steem, and a little LBRY. I do think I want some DASH in my portfolio after I finish paying off my debt and start investing.
