Where can I buy a Gemini Dollar?

I'm curious, where exactly can I purchase a Gemini Dollar? I've heard a lot about this stablecoin and its potential for use in various financial transactions, but I'm not sure where to start looking. Are there any specific exchanges or platforms that support the trading of Gemini Dollars? Or are there any restrictions or requirements I need to be aware of before making a purchase? Any information you can provide would be greatly appreciated.
