Excuse me, I'm interested in investing in the emerging field of artificial intelligence and have heard about the potential of OpenAI. Could you please guide me through the process of acquiring an OpenAI coin? I'm a bit confused as I've searched online and haven't found a direct way to purchase one. Is there a specific exchange or platform I should be looking at? Also, are there any regulatory considerations or risks I should be aware of before making such an investment? I'd greatly appreciate any insights or advice you can offer.
