Why is OKX not available in the US?

I'm quite puzzled why OKX isn't accessible in the United States. Given its popularity and the thriving cryptocurrency market in the US, it seems like a natural fit. Could you shed some light on the reasons behind this decision? Are there any regulatory issues or compliance challenges that have precluded its entry into the US market? I'm really interested in understanding the reasons and perhaps even exploring potential solutions that could make OKX available to US users.
