I believe that the USA. won't let cryptocurrency companies to move out of their country easily and because of SEC.
I don't have any information about Coinbase wanting to leave the USA. Can you elaborate more on those rumors?
The Security and Exchange Commission must fight all the centralized crypto scams and punish any shady and sketchy practices that are being conducted by some of the big crypto companies. While doing this, the SEC must not destroy the entire cryptocurrency industry in the USA.
Coinbase can sue the SEC if they want. I guess that they can hire a good team of lawyers and they have gathered enough evidence to prove their claims in court. Otherwise deciding to sue the SEC would be a massive mistake.
It's all just rumors, and they say that if the US continues to pressure and embarrass them, they will move to another country with friendlier laws.
Binance has also made this point, but it's all just a rumor.
In my opinion, the SEC is looking for a way to blame crypto and then legally control the market instead of destroying it completely. Destroying the market is not in their favor, they have seen the benefit of the market, and they do not want it to fall into the hands of another regulator like the CFTC. As far as I know, both are vying for control of the cryptocurrency market.
