There is nothing like hype when it comes to stable coins and may be you are not getting it, stable coins are pegged to something that is physically backed and there is no way we can see an increase in value since it is controlled. So the being valuable of a thing is not at all some necessary factor to be looking at, considering that the main reason they are available is to be able to hedge funds that is all.
As long as the stable coins popping up does not end up like tether in the long run, and they give room for transparency, which is an edge most of them are having over tether, then there will be no cause for alarm.
