I think we have to look at what's the real purpose of stable coins in the market? Will it bring that "stability" or will it make us confused more with their usage, specially noobs in the market. And we all know that the number 1 stable coin today has a lot of accusations of manipulations in the past. Obviously, Tether and Bitfinex has denied and said. that this is baseless. But if this stable coins allegedly is playing the market around then we might need some alternatives.
We have to get other options so we can differentiate and know what's better for us. Yes, there's a lot of manipulation on Tether whether they admit it or not but we know its happening. If there's so many stablecoins then at least we can have an assurance to make money while the market is full of risk.
If there's more stablecoins to come, maybe many businesses will adopt it since we know the problem on a slow production is simply because of the high volatility, that prevents them to adopt.
