Increasingly I have seen concern about the dystopic scenario in which the dollar collapses. And although such a scenario is very unlikely (unless we consider a time scale in the order of decades) it is frequent to see responses that point out to possible collateralization in terms of another currenciesand even different assets.
Perhaps the most realistic answer comes this way:
(1) If USD inflation occurs, that would mean an increase in the price of ETH in relation to USD.
(2) Of course, a bull market would mean more people doing leverage in the hopes of acquiring more ETH as explained in past comments. However, doing so would mean less people holding HyperUSD, for example.
(3) The only way to keep the price of stable would mean increasing the Stabilization Fee.
The collapse of the dollar is extremely unlikely to occur. Cases of hyperinflation are created usually by governments trying to find their way out of debt by printing a thumping amount of fiat. This occurs when their economy of course is not dominated by their own currency.
I believe that if the USD were to experience hyperinflation, the only way to maintain the peg to the USD would be to increase HyperUSD circulation proportionally. That would have as a consequence that the Saving and Stability Fees had to be reduced.
