Hard to disagree with that. I think the hope is that with more users, volatility will diminish. That is what usually happens with markets.
Ultimately, we might see STEEM, as an example, as the currency for commerce on the entire platform. Of course, there is always SBD but that is as volatile, if not more, than STEEM.
Yes, SBD needs to be re-worked to better hold its peg if it is ever to have much utility.
