I remember the Increasing the total supply of SafeCoin thread. And it may be on the list of ideas. But right now, I don’t see it as part of the RFC, which tells us what the devs are planning to work on.
@krnelson constantly calls for a “single” currency, divisible by default. I’m inclined to agree with him.
Gold ~> Silver ~> Copper… might seem intuitive to many people because it’s part of a 5000 year history.
My SAFE GB idea uses a similar history (GB being well known) and even that was a bit difficult.
But we are creating a new currency with no reference. It would be easiest for new people to start with just 1 denomination of SC.
