Is the SEC pursuing enforcement actions against unregistered crypto trading platforms?

Excuse me, but I was wondering if you could elaborate on the current stance of the Securities and Exchange Commission (SEC) towards unregistered cryptocurrency trading platforms. Are they actively pursuing enforcement actions against these platforms, and if so, what specific measures are they taking to ensure compliance with securities laws and regulations? Is there any concern within the community that the lack of oversight over these platforms could lead to fraudulent activities or harm investors? I'd appreciate any insights you could provide on this matter.
