The thing is, Digix cannot mint any DGX if there is no physical Gold / Silver tokenize. If DGX is in high demand, the supply must balance it, otherwise, price surges and so much for stability. Similar case with Bitcoin, the higher the value, lesser the retail use of it. Most just HODL. That isn't good for currency.
As I understood for the USD, the economy needs liquid and government cannot print any without gold. That's a deadlock situation until Nixon, temporarily permanent pause the Bretton Woods system.
I don't think DGX will surge in case of low supply, but we'll see. I think DGX will act very differently from other cryptocurrencies, although wait and see is all we can do.
I agree, time will tell.
Price will go up when demand outweigh supply. Otherwise, stagnate coin is not going good as currency. No dispute on the store of value for DGX, but currency without the current isn't promising.
In the meantime, we can only reflect on history lessons.
