The biggest challenge to all these stablecoins is the transparency and confidence and one way to resolve that would be the display of funds in fiat of the stablecoin bank account to public every week or month or the bank account should be put online and public where anyone can check the value and match it with the supply of the stablecoin this strategy will boost interest, trust, confidence and investments into these stablecoins.
I agree. that's why I can't support fiat coins because of the lack of transparency. I do see that ampleforth offers a very unique solution since it's an elastic supply protocol.
