I think you are getting something wrong here.
The issue between Binance and the SEC has nothing to do with Bitcoin; the reason it has a slight impact on the Bitcoin market is because Binance is one of the most popular centralized exchanges.
Even if Binance is seized or prevented from operating, Bitcoin will continue to move since it is not dependent on any other coin, unlike altcoins, the market price of which is dependent on Bitcoin's.
Maybe the original poster's view is not clear to you because it think his observation and questions are valid. Last year the fall of FTX and some other crypto-related firms affected the price of Bitcoin. The price dropped because of the FUD it caused. So Op is surprised that the attack on one of the biggest exchanges is having little or no effect on the price of Bitcoin.
The reason why the bitcoin market is not reacting so much to the SEC and Binance issue as much as we may have expected is because it appears to be more of a social attack rather than a direct attack on bitcoin network protocol, mining operations or blockchain technology. The market would have reacted differently if it was an attack on the network. Am I correct? I don't know much about the technical aspect of Bitcoin, but this is the best possible explanation I can think of for what is happening. Is there anyone else who shares the same sentiments?
My observation is that:
1. Bitcoin is becoming independent from the influence of exchanges and crypto-related businesses.
2. The market was ready for the SEC onslaught against Binance because it has been expected for a long time.
3. This legal battle will only affect Binance US so other nations are stable and attack-free.
4. More people are becoming aware of decentralized wallets so they are not affected by the problems of exchanges.
