Oh. I see @dragosroua. I understand the trade off now.
That has answered a question I had about why anyone would sell goods using crypto as a currency when it is so volatile. I just couldn't see how it would work. But now I see that that is the point of SBD.
So the bit that really remains to be seen then is, whether or not, SBD can truly be pegged to the dollar. There seem t be those who believe that it can't.
I've taken a step forward today in my understanding of this. Horrah! and thanks. 😊
