I think it's more likely for Binance to cease western operations, disregard the SEC and continue operating in european and eastern markets in comparison to Coinbase operating elsswhere.
Currently, if you look at developments from some time ago, Binance has faced scrutiny and warnings from regulatory authorities in several countries, including the US. If Binance stops its operations in the Western market, I think it has the potential to affect the trust and confidence of investors, especially those who are more concerned with regulatory compliance. If Binance ignores the SEC and continues to operate in European and eastern markets as you said above, it may could be. But, I think it could face legal consequences that could hinder Binence's operations and reputation. Going forward, going backwards is hitting Binence.
Yes, they have. And every time they basically evade consequence and find a way around it.
The only reason why Binance continues to survive is because they are at minimum quietly supported by Chinese/eastern governments, and at maximum already an asset used by governments and closely working with CZ in the goal to retain economic power.
With this in mind, they can easily leave the US, or ignore the SEC, and continue to operate (probably wherever they want). What are the SEC going to do about it? Kick and scream in the media? Try to take them to international court? Maybe both...but until the judge slams the hammer they'll still continue to operate.
I think everyone severely underestimates the amount of economic and political power Binance have, and have behind them.
