Just like what others said, why do we even need more stable coins? I think those who are trying to create more coins should stop; it's just diluting the market, and more people would see as cryptocurrency is just a joke or something. The effort takes to create one is not that hard, and scammers are taking advantage of that.
The main effort should go to the adoption phase for different countries. Mainly, the most accepted stable coin would be the start Currency for any country, and hopefully, people won't see cryptocurrencies as a joke just because of the scams.
